Surveys suggest that more than half of cats in the United States are overweight or obese. Your cat may look rather charming with a bit of chub, but the health problems that come with it are considerably less so. Overweight cats are more prone to diabetes, arthritis, urinary problems, and some forms of cancer, they carry greater risk under anesthesia, and they tend not to live as long. Heavier cats also struggle to groom themselves properly, which leads to matted fur and skin problems—usually along the back and near the tail base, where they can no longer reach.
As your cat's veterinary team, we'd like to help you give your cat the healthiest life possible. We see a great many patients with weight-related problems, and the good news is that this is one of the most preventable things we deal with. Here's how we can work on it together.
Understanding Your Cat's Dietary Needs
Cats come in a range of shapes and sizes, so one cat's healthy weight might be too much for another. That's why we assess weight using a body condition score rather than the scale alone.
What you can check at home:
- Ribs. You should be able to feel them fairly easily with a light touch, with only a thin covering of fat over them.
- Waist. Looking down at your cat from above, there should be a visible narrowing behind the ribs.
- Profile. From the side, the belly should tuck up slightly rather than sagging or swinging.
- Neck and shoulders. There should be a clear distinction between head, neck, and shoulders.
If you can't find the ribs without pressing, or there's no waist, it's worth a conversation with us. We'll weigh your cat, score their condition, and set a realistic target—and it's worth weighing them at home every month or two on a kitchen or baby scale, since a cat can gain a pound before it becomes visible. On a ten-pound cat, that's the equivalent of a person putting on fifteen.
Once we know where your cat stands, we can work out how much they actually need, taking into account their age, activity level, whether they're neutered, and any health conditions. Measuring meals properly makes a real difference—use a measuring cup or, better, a kitchen scale, and treat the guidelines on the packaging as a starting point rather than a prescription, since they tend to be generous.
An Important Note on Weight Loss in Cats
Before changing anything, please talk to us—this matters more in cats than in dogs.
Cats need to lose weight slowly, and a cat who loses weight too quickly, or who stops eating because they dislike a new diet, can develop hepatic lipidosis, a serious liver condition. Crash dieting a cat is genuinely dangerous, so weight loss needs to be gradual and monitored.
It's also worth ruling out a medical cause first. Weight gain can accompany hypothyroidism, and unexplained changes in appetite or weight in either direction are worth investigating. Equally, a cat who is losing weight without you changing anything needs seeing promptly—that's often the first sign of hyperthyroidism, diabetes, or kidney disease.
Don't Allow Unrestricted Access to Food
Filling a large bowl or a dispenser and leaving it out all day is convenient, and it's one of the main contributors to feline obesity.
You may have heard that cats self-regulate and stop when they've had enough. It's a persistent idea and it isn't reliable—your cat probably won't clear the bowl in one sitting the way a dog might, but over a day they'll generally eat more than they need. Neutered indoor cats in particular need fewer calories than most owners expect.
Measured meals at set times work considerably better. Two to four small meals a day suits most cats, and it also lets you see how much your cat is actually eating—which is genuinely useful information, since a change in appetite is often the first sign that something's wrong. It may take a week or two for a cat used to grazing to adjust, and we can guide you on amounts and timing.
If you have more than one cat, feed them separately, in different rooms if necessary. Otherwise the confident eater finishes their own bowl and starts on someone else's, and you have one cat gaining while another goes short.
Encourage Exercise
Inactivity is a major factor in feline obesity, particularly in indoor cats. Keeping your cat inside is far safer, and the trade-off is that lounging on the sofa doesn't burn what stalking around a neighborhood does.
The good news is that cats don't need long sessions—they hunt in short bursts, so several five-minute play sessions through the day work far better than one long one. Wand toys with feathers are the reliable favorite, and the trick is to move them like prey: darting, pausing, and hiding, rather than sweeping steadily back and forth. Finish each session by letting your cat catch something, so the hunt ends in a result rather than in frustration.
Beyond burning calories, play offers other benefits:
- It relieves boredom, which reduces problem behaviors
- It's an excellent way to strengthen your bond
- It satisfies the hunting instinct that indoor cats have no other outlet for
- It provides mental stimulation and can reduce stress
You can also make food work harder for your cat. Food puzzles and treat balls turn a meal into a task, and simply splitting the day's ration into small portions hidden around the house means your cat has to go looking for it—which is closer to how they're built to eat. Vertical space helps too: perches and a cat tree encourage climbing and jumping, and give an indoor cat somewhere to be other than the sofa.
Do build up gradually with a very overweight cat, and let us know if yours is elderly or seems stiff. Arthritis is extremely common in older cats and frequently missed, and a cat who has stopped jumping onto their favorite windowsill may be in pain rather than simply lazy—which is worth sorting out before you encourage more activity.
Don't Be an Automatic Treat Dispenser
We know you love your cat and want to make them happy, but treat after treat isn't the way. Even with the right food and a sensible meal schedule, treats can undo the whole plan—they should account for no more than about 10% of your cat's daily calories, and it's remarkable how quickly they add up.
Count everything, including what other members of the household hand out, and if you're using treats, use very small pieces. A cat doesn't measure generosity by size.
When your cat asks for a snack, it's worth considering that they may be asking for attention rather than food. A play session with a favorite toy, some head scratches, or a brushing session often satisfies the request perfectly well—and if your cat has learned that meowing produces food, expect them to try harder for a while before they give up on it.
Schedule Routine Wellness Care
Regular wellness exams are the most useful thing you can do here. They let us track your cat's weight over time, spot gradual changes you might not notice seeing them every day, and check body condition properly. If your cat is gaining weight despite a sensible diet and plenty of activity, bloodwork can help us work out why.
How often depends on your cat—healthy adults are generally seen once a year, and cats over about seven benefit from twice-yearly visits, since a great deal can change in twelve months at that stage.
Whether it's been a while since your cat's last checkup or they need help losing a few pounds, we're glad to help. Contact us today to book an appointment.
