The vision thing: What do cats and dogs actually see?

Centuries of domestic breeding have resulted in cats and dogs that come in a wide variety of shapes, sizes, and colors. If you have a favorite breed, there’s a good chance that you like it to some degree because of the way it looks. But what do our pets see when they look back at us? In truth, they see better than us using multifocal contact lenses.

Let’s clear up the most common misconception first. Dogs do not see in black and white. They do, however, see a different color spectrum. This is because their retinas—the light-detecting membranes at the back of the eyes—are built differently. Human retinas have three types of light-sensitive cells called cones, each of which is tuned to a single color: red, blue, or green. Dogs have only red and blue cones, which makes their vision similar to that of a person with red-green color blindness.

Like humans, cats have three types of cones, but they still don’t see color all that well. This is because cats and dogs have another problem with color vision: Regardless of which cones they have, they don’t have very many of them. Instead, their retinas are packed with a different kind of light-sensing cells, called rods, that don’t detect color at all. Rods are better suited to seeing in dim light than they are to parsing the hues of rainbow. People have fewer rods than cones, so while we get to see the daytime world in bright color, we are fated to stub our toes searching for the toilet at night.

But all those rods aren’t the only reason why cats and dogs can see so well in the dark. You’ve likely noticed your pets’ eyes glow bright green at night. This is courtesy of the tapetum lucidum, a reflective layer behind the retina. Any light that slips through the retina bounces off this secondary layer for another pass through the animal’s retina, effectively doubling its sensitivity.

There’s more to vision than color and brightness, however. Compared to people, dogs and cats have limited visual acuity. Dogs have roughly the equivalent of 20/75 vision, meaning they need to be 20 feet away from something to see it as well as a normal person could at 75 feet. And you may be surprised to hear that cats fare even worse! Those sleek and gorgeous eyes seem built for precision, but cats are close to legally blind with vision somewhere around 20/150!

Making matters worse, dogs and cats have trouble adjusting their vision to different distances. This is because their lenses can’t adjust shape as readily as ours can. If you’re over 40, you’re familiar with what happens when your lenses start to become inflexible. It gets harder and harder to focus on anything close to your face. Welcome to life as a dog.

The short of it is that cats and dogs see better at night than we do, but those adaptations come at the cost of clarity. But poor vision doesn’t slow them down any. They don’t need to drive cars or read the fine print. And what they lack in eyesight, they make up with magnificently superior senses of smell and hearing. Even animals that lose their vision due to degenerative diseases do incredible job of navigating their homes, because their vision was never that great to begin with.

Oh, snap: Addressing ligament injuries in dogs

Nine times out of 10, you know this injury the moment you see it: A large-breed dog hobbles in on three legs, with one hind paw dangling just above the ground. It could be a fractured leg or a dislocated hip, but if I were playing the odds, I’d bet it’s a ruptured cranial cruciate ligament.

A quick comparative anatomy lesson is in order. Just like people, our pets have knee joints in their hind limbs (and only in their hind limbs). The human knee is partly held together by a pair of criss-crossing ligaments called the anterior and posterior cruciate ligaments (ACL and PCL). The same is true in dogs, except the nomenclature is different. Instead of a knee, we call it a stifle. And instead of anterior and posterior cruciate ligaments, we say cranial and caudal.

Regardless of what you call it, if a dog injures a cranial cruciate ligament it has the same problem as a human with a torn ACL: The joint simply isn’t being held together anymore. Sometimes this injury is purely the result of trauma. Just as people can rupture an ACL while skiing or turning too quickly on a basketball court, dogs can blow the ligament by just running around in the yard. But that’s not how it usually happens.

Far more often, a pre-existing joint disease contributes to a dogs’ cruciate ligament injury. While my patients may suffer sudden lameness after exercise, the groundwork for that injury was almost always laid down in advance. Degenerative joint disease is common in the stifle, and that constant inflammation weakens the cruciate ligament. With hindsight, many owners recall their dogs showing intermittent lameness in the prior weeks and months. It improved after a few days of rest, but with each round of exertion, the ligament weakened until finally giving out.

This brings good news and bad news. First, the good: Preventing degenerative disease can reduce the risk of cruciate injuries later on. The single best way to do this is to make sure dogs maintain a healthy weight and engage in routine low-impact exercise like walking and swimming.

The bad news is that degenerative joint disease results from a convergence of environmental and genetic causes, many of which are not well understood. Although weight is a factor, it is not the most important one. Some dogs just seem destined to have bad joints. So while you might be able to reduce the injury’s odds, you can’t eliminate them.

Once a dog has been diagnosed with a cruciate injury, options can be frustratingly limited. Smaller dogs can sometimes recover with time and rest, but the joint often remains unstable and prone to re-injury. Larger dogs very rarely respond well to conservative efforts, and the majority of dogs with cruciate injuries cannot recover without surgical repair. And worse, since the underlying causes affect ligaments on both sides, an injury to one is very likely to eventually injure the other one. Delaying treatment can multiply their troubles since overuse of the opposite leg steadily increases the odds of both legs being affected.

While the prospect of knee surgery can be emotionally and financially stressful, I’m at least happy to say that the results are broadly excellent. Orthopedic surgery is increasingly the province of highly-trained specialists, and nearly all of these dogs eventually return to a happy and active life. That doesn’t make the news of a cruciate injury any more welcome, but it hopefully makes it a little less daunting.

Cat pause: If your pet has a terminal virus, don’t panic

Animals have a remarkable knack for stealing our hearts, and it doesn’t take long to develop a deep emotional bond with a new pet. This makes it all the more distressing to find out that a seemingly healthy young cat is harboring an incurable and potentially fatal illness. It is unfair but unfortunately common with the feline immunodeficiency virus and feline leukemia virus.

FIV sounds like HIV, which is apt and can give you a decent sense of what the virus does. It is often referred to as feline AIDS, but just as with the human infection, this term only properly applies to the syndrome that occurs in the later stages. Until that happens, infected cats may show little or no evidence of the illness. But their immune systems are generally compromised by the virus, leaving them vulnerable to other infectious diseases and parasites. After a positive diagnosis, cats should receive frequent checkups to detect and treat secondary illnesses.

Cats with FeLV may also have suppressed immunity, but the virus ultimately gets its name from its ability to cause cancer in its victims. The virus replicates by inserting its DNA into the animal’s host cells, and the genetic mutation can cause infected white blood cells to lose control of their own replication, resulting in leukemia or lymphoma.

Both FIV and FeLV require close contact (such as mutual grooming) or biting to transmit, and they’re fragile outside their hosts. (Don’t worry, the viruses are not transferable to humans.) Infected cats should be kept indoors not only to avoid challenging their weakened immune systems, but also to prevent the infection of other cats.

Most veterinary clinics can test for these viruses with a simple in-house kit, but testing often falls by the wayside once cats have tested negative as kittens. This is potentially dangerous, especially in cats demonstrating chronic or recurring illness. False negatives are possible depending on the exact stage of infection, and it is important not to be complacent just because a cat tested negative years ago. While routine testing may not be warranted for healthy indoor cats, it can be valuable for those who are sick or spend a lot of time outdoors, where they might get into a scuffle.

Both viruses have vaccines, but their use is not cut and dried. The FIV vaccine can be wise in certain at-risk patients, but it comes with a big hitch in that it interferes with all common means of testing. Cats that have been vaccinated for FIV will test positive for infection. But since the vaccine is only about 80 percent effective, this makes for potential confusion if a pet develops worrisome symptoms after getting a dose.

It is far easier to recommend the FeLV vaccine for patients with a higher risk. Although the vaccine is also not perfectly effective, it does not interfere with testing, so we don’t lose clarity down the line. It only has an upside.

If you find yourself confronted with either diagnosis, it’s important to take a breath. The news is undeniably unfortunate: Neither virus is curable, and infected cats are likely to require more veterinary care to screen for trouble and to fend off secondary illnesses. But a pet owner should not let concern spiral into despair: Infected cats often experience many years without any symptoms at all, even into old age.

One of the joys of having pets is the perspective they bring. Even when their own health is endangered, they take life one day at a time and remind us to do the same. And in this case, there may well be a lot of good days to come.

Holiday hazards: Keeping pets safe for the season

The holidays must be a weird time for our pets. Their familiar homes are suddenly brimming with strange trinkets and lights. New smells are wafting in from the kitchen. And did I mention there’s a tree in the living room? While most pets adapt quickly to our inexplicable traditions, a few will find ways to get into trouble.

Perhaps the first thing that comes to mind is the poisonous potential of the season. From baked goods to little foil-wrapped Santas, there is a whole lot of chocolate around this time of year. While small amounts of chocolate aren’t as toxic as you might fear, no self-respecting dog is going to stop with just one bite. It’s a good idea to keep that box of candy on the countertop instead of the coffee table.

Poinsettia plants are another inescapable Christmas symbol, and are widely known for their toxicity. Thankfully, their reputation is generally unearned. These plants can be minor irritants and can cause some stomach upset, but don’t present a life-threatening danger. It’s still wise to keep them out of reach, but there’s no need to banish them from your home.

Other holiday décor can be irresistible to curious animals. Dogs may try to snack on low-hanging ornaments, and what cat wouldn’t want to climb his own personal tree? Strings of lights and other electrical decorations can pose the risk of burns or electrocution if bitten. Depending on your pets’ personalities, you may need to find creative ways to keep them away from your newly decked halls, or reconsider what decorations you choose.

When it comes time to open gifts, keep your animals in mind. Ribbons and strings look nice on a present, but can quickly obstruct the intestines of pets that consume them. As gifts are unpackaged, twist ties and plastic bags left out can be a choking or asphyxiation hazard. And animals may not be able to tell the difference between a child’s new treasure and a chew toy.

Setting aside these holiday trappings, it’s also a time of year to gather with friends and family. While many pets relish the company, anxious animals may find the chaos stressful. The constant arrivals and departures can trigger dogs’ protective tendencies or allow flighty animals to escape. And the sudden presence of children (who, let’s be honest, can get a little intense under the influence of Christmas) may increase the risk of bites and scratches. If there’s any doubt at all, it’s best to keep animals safely elsewhere until things calm down.

Animals are inherently festive, and they can bring a lot of joy to the season. But there is a lot going on this time of year, and much of it can be confusing for our pets. Most seasonal hazards require a bit of mindfulness to avoid, but with a house full of guests and dinner cooking in the kitchen, it’s easy to get distracted just long enough for trouble to start. Taking a moment in advance to identify potential problems can make it easier to relax once the celebration really begins.

Control issues: New restrictions on prescribing opioids for pets

It’s been hard to escape news of the opioid crisis over the past few years. And it’s just as difficult to ignore the complicity of the nation’s health care system in creating it. Opioid medications—drugs similar to morphine and named for the opium poppy plant that produces them—have an important role to play in patient care. Used correctly, they are vital tools in controlling pain and suffering. But they have not always been used correctly, and the resulting addiction crisis has come at great cost in dollars and, more importantly, lives.

These drugs are also used in veterinary medicine. The past few decades have seen an increased emphasis on pain management in veterinary patients, and I believe that is a good thing. Short-term use of opioids is a safe and effective way to control acute pain associated with things like surgery or trauma. The danger comes with long-term use, as opioid receptors in the brain become accustomed to the drug and demand more of it.

There remain, however, many cases where long-term opioid use is justified. Some animals have concurrent medical conditions that preclude use of non-opioid alternatives. And sometimes, it’s the only thing that works. While animals can become addicted in theory, it is uncommon in practice. They simply have no control over their own dosing, which limits the potential for escalating abuse.

Recent changes in Virginia state law have established a prescription monitoring program that creates a consolidated database intended to track use and misuse of controlled drugs. This includes opioid medications like tramadol, and even some non-opioid medications like gabapentin that have the potential for abuse. These laws extend to veterinarians and have resulted in significant changes in the way we can prescribe these medications. The concern isn’t that animals are becoming addicted, of course. It’s that these drugs might be diverted for human use.

Veterinarians were given two options to comply with this program, and the first—submitting daily reports of all controlled substances prescribed—just isn’t feasible for most practices. Instead, most have elected to accept a waiver that limits them to dispensing one week of medication. If more than that is required, it must be prescribed through an external pharmacy so it can be monitored appropriately. It also requires that these animals be evaluated at least once every six months to keep the prescription active.

What does this all mean for pet owners? Mostly, it means that things are less convenient than they were before. If your pet requires ongoing use of a controlled substance, it is important to make sure that she is seen by her vet every six months. Your vet may be able to help by sending an automated reminder. It is also important to request refills well before your current supply runs out to avoid problems and delays.

I don’t know how much of a role veterinarians really play in the opioid crisis, but we’re wrapped up in it all the same. While these drugs shouldn’t necessarily be feared, they deserve respect and care in their use. Inconvenient as they may be, these new regulations are intended to make sure that care is taken.

The tangled reality of hairballs

I’ve always been a sound sleeper. Garbage trucks? Thunderstorms? Please. But the low, glugging sound of my cat depositing a hairball three rooms away can wrest me from the deepest slumber in an instant. It’s as if that noise is wired directly to the sleep center of my brain.

Most cat owners are somewhat familiar with these grudging bouts of nocturnal carpet-cleaning. Sometimes you just find a few wisps of hair wet with bile. Other times, you recover a big furry slug, technically known as a trichobezoar (hideous regardless of what you call it). But is it true that hairballs are just a normal part of being a cat? But how much is too much? The answer is, so to speak, fuzzy.

Hairballs may be common, but that doesn’t mean they are normal. While hair is ingested as part of regular grooming, it is meant to pass straight through like everything else. If too much hair accumulates in the stomach at once, it may come back up as a hairball. But in a healthy cat, these instances should be infrequent. Serial offenders likely have a broader underlying problem.

It stands to reason that cats who consume more hair are more likely to produce hairballs, so the first thing we look for is evidence of excessive grooming. Cats may ingest too much hair while tending to fleas, allergies, or other skin conditions. And others may overgroom as a response to psychological stress or anxiety.

If a cat isn’t swallowing too much fur, the next worry is that the gastrointestinal system is doing a poor job of handling it. Inflammatory bowel disease is a common underlying problem in cats, and frequently comes with liver or pancreatic disease in tow, requiring varying degrees of medical and dietary intervention.

Confusing things further is that unrelated conditions can be misinterpreted as hairballs. People frequently describe “coughing” and “hacking” when they suspect their cat might have a hairball, but these verbs can be ambiguous and misleading. Hairballs are vomited, not coughed. A coughing cat is more likely to have a respiratory condition like asthma than a hairball problem. In these cases, video of an episode can be invaluable in making sure that diagnostic efforts get started on the right track.

None of this is to say that every cat who pukes up a hairball, or even several, needs a massive medical investigation. Hairballs may be abnormal, but so long as they are infrequent, they may represent minor, transient upsets. We all have our bad days. But if a pattern starts to emerge, or if those hairballs are seen alongside other symptoms like weight loss, it may be time to consider underlying causes before they get out of hand.

The management of hairballs is not one-size-fits-all. Commercial hairball diets and supplements are intended to grease up hairballs and allow them to pass normally, but their efficacy is dubious. Brushing your cat regularly may help by reducing the amount of hair ingested during grooming, especially in long-haired cats. But when it comes down to it, the best way to manage hairballs is to discover and address the root cause.
