How to Keep Your Cat Healthy: 9 Habits That Actually Make a Difference

Figuring out how to keep your cat healthy doesn't have to mean clinical blood panels or vague 'just love them and they'll be fine' advice. The reality sits in between: cat health is mostly a handful of ordinary daily habits, done consistently, long before anything shows up at the vet.

We’ve been figuring this out with Momo and Cleo, our two rescue cats, for years now. Here’s the full list of what actually moves the needle, the small daily habits, the things worth watching for, and where a product or two genuinely earns its place in the routine.

1. Feed a Balanced, Species-Appropriate Diet

Cats are obligate carnivores, their bodies are built to run on animal protein, not the grain-heavy fillers found in a lot of budget cat food. Diet quality shows up everywhere: coat condition, energy, digestion, even litter box habits.

• Choose a food with a named animal protein (chicken, salmon, turkey) as the first ingredient, not “meat by-product” or “meal”

• Transition to a new food gradually over 7–10 days to avoid stomach upset

• Skip the milk, most adult cats are lactose intolerant despite the stereotype

• Talk to your vet before any major diet change, especially for cats with existing health conditions

This is also the one area where we’ve found a small daily addition makes a real difference. Stylla Hydration for Cats is a liquid supplement, a blend of amino acids (proline, glycine, threonine) that make water taste better to cats without any diuretic effect, so you add one pipette to the water bowl once a day and cats drink more without any coaxing.

2. Keep Your Cat Properly Hydrated

Chronic mild dehydration is one of the quietest problems in indoor cats, and it’s tied to two of the most common feline health issues: urinary tract problems and kidney disease. Cats descend from desert animals with a naturally low thirst drive, so they don’t always drink enough on their own, especially on a mostly-dry-food diet.

• Add a second (or third) water bowl in a different room, cats often won’t walk far for water

• Try a cat water fountain, moving water gets more attention than a still bowl

• Mix in wet food a few times a week, it adds real moisture on top of drinking

If your cat is a stubborn drinker even with a fountain in place, a taste-based approach can help more than a new bowl will. Stylla Hydration for Cats is a liquid supplement, a few amino acids (proline, glycine, threonine) that make water more appealing to a cat’s taste receptors, added to the water bowl once a day with no diuretic effect. It’s the one product swap in this whole guide that made a measurable difference for us.

3. Maintain a Healthy Weight

Feline obesity is one of the most common, and most preventable, health issues in indoor cats, and it quietly raises the risk of diabetes, joint problems, and a shorter lifespan. Because the weight gain is usually gradual, it’s easy to miss until a vet points it out.

• Measure food instead of free-feeding, even “a little extra” adds up over a year

• Use a puzzle feeder to slow down fast eaters and add activity to mealtime

• Do a monthly hands-on check, you should be able to feel ribs without pressing hard

• Not sure where your cat stands? Our guide on how to tell if your indoor cat is overweight walks through it step by step

4. Prioritize Dental Care

Dental disease affects a majority of cats by age three, and it’s easy to miss because cats are experts at hiding pain. Left untreated, it can lead to tooth loss, infection, and pain that quietly affects appetite and mood.

• Brush a few times a week with a cat-safe toothpaste, even occasional brushing helps

• Offer dental treats or a water additive designed to reduce plaque buildup

• Watch for bad breath, drooling, or pawing at the mouth, all worth a vet check

• Ask your vet about a dental cleaning if tartar is visibly building up along the gumline

5. Stay Current on Parasite Prevention and Vaccinations

Indoor cats still need protection. Fleas hitch a ride in on shoes and other pets, and mosquitoes (which can transmit heartworm) get in through an open window or a screen door.

• Use a vet-recommended flea and worming treatment on schedule, even for indoor-only cats

• Keep core vaccinations current, your vet can advise on the right schedule for your cat’s age and lifestyle

• Bring a fresh stool sample to annual checkups if your vet screens for intestinal parasites

6. Support Mental and Emotional Wellbeing

Stress in cats doesn’t stay emotional, it shows up physically: overgrooming, appetite changes, litter box avoidance, even flare-ups of conditions like feline idiopathic cystitis. A chronically stressed cat is a cat whose body is working overtime.

• Keep feeding, play, and sleep times predictable, cats regulate off routine

• Give every cat a few safe, elevated, or enclosed spots to retreat to

• Schedule real interactive play, not just toys left out on the floor

• Introduce any change (new pet, furniture, guest) gradually, not all at once

Our full breakdown of how to keep an indoor cat happy goes deeper on enrichment specifically, and it pairs well with everything in this section.

7. Keep Up With Regular Vet Checkups

A lot of feline illness is manageable, if it’s caught early. Cats are also very good at masking symptoms until a condition is fairly advanced, which is exactly why routine visits matter more than reactive ones.

• Aim for an annual checkup for healthy adult cats, and every six months for seniors (7+)

• Ask about routine bloodwork starting around age 7, it catches kidney and thyroid issues early

• Track any new symptom for a day or two, but don’t wait weeks to mention it

8. Groom Regularly

Regular grooming isn’t just about a shiny coat, it’s a hands-on health check in disguise. Running your hands over your cat weekly means you’re far more likely to catch a new lump, a hidden wound, or a sudden weight change early.

• Brush a few times a week to reduce shedding and hairballs, more often for long-haired cats

• Check ears, paws, and teeth during grooming sessions, not just the coat

• Trim nails every few weeks to prevent overgrowth and snagging

9. Know the Warning Signs Worth a Vet Visit

Most day-to-day health maintenance is genuinely low-drama, but a few changes are worth acting on quickly rather than waiting to see if they pass.

• A noticeable drop in appetite or water intake lasting more than a day

• Vomiting or diarrhea that continues past 24 hours

• Straining in the litter box or not urinating, this can be a medical emergency in male cats especially

• Sudden lethargy, hiding, or a personality shift

• Rapid weight loss or gain, or a new lump or swelling

How to Keep Your Cat Healthy – The Takeaway

Cat health isn’t one big decision, it’s a dozen small, boring, repeatable habits: good food, enough water, a stable weight, clean teeth, a low-stress home, and a vet who sees your cat before something becomes an emergency.
