Most cat health problems don't appear overnight. They build quietly over months — a gradual weight change here, a shift in grooming there — until something obvious forces a vet visit. This checklist is organized by category so you can run through each area quickly and systematically, whether you're a first-time owner building a routine or an experienced cat owner looking for a structured reference. Use it monthly, and you'll catch problems while they're still inexpensive to fix.
Nutrition Checklist
Food quality: The first five ingredients on your cat food label tell you most of what you need to know. The first ingredient should be a named animal protein — chicken, salmon, turkey — not "meat by-products" or a grain. Cats are obligate carnivores; they require taurine, arachidonic acid, and vitamin A from animal sources and cannot synthesize them from plant matter. Brands with strong nutritional track records include Purina Pro Plan, Royal Canin, and Hill's Science Diet — all available at Chewy, Petco, and major retailers, and all backed by AAFCO feeding trials rather than just formula calculation.
Portion control: Are you measuring? Most overweight cats got there through free-choice feeding with dry food. Measure meals using the guide on the packaging, adjusted for your cat's current weight. Most adult cats need between 200–280 calories per day; check the caloric density on the bag. If your cat acts hungry all the time on measured portions, switch to a higher-protein, lower-carbohydrate wet food formula — protein and moisture are more satiating than dry kibble for most cats.
Wet food inclusion: Is your cat getting at least one wet food meal per day? Cats evolved getting most of their hydration from prey, not from a water bowl. Chronic low-level dehydration contributes significantly to kidney disease — the leading cause of death in geriatric cats. Even one wet meal daily meaningfully increases total fluid intake. Warning: Avoid fish-based wet foods as the primary diet; high fish intake long-term has been linked to thiamine deficiency and has potential associations with hyperthyroidism. Rotate proteins.
Grooming Checklist
Coat condition: A healthy coat lies flat, feels smooth, and has a slight sheen. Dullness, excessive shedding, or a greasy feel suggests nutritional deficiency, parasites, or an underlying health issue. Long-haired breeds — Persians, Maine Coons, Ragdolls — need brushing at least twice weekly to prevent mats that, once formed, require veterinary clipping. Use a Furminator deShedding Tool for short-haired cats weekly, and a wide-toothed metal comb for long-haired breeds to work through the undercoat without breaking the outer guard hairs.
Nail length: Trim every 3–4 weeks. Overgrown nails curl under and grow into the paw pad — painful, avoidable, and increasingly common in older cats who wear nails down less through reduced activity. Use cat-specific clippers; human nail clippers compress the nail instead of cutting cleanly, which splits the nail and causes discomfort. Zen Clipper and Safari Cat Nail Trimmer are both widely available and well-reviewed on Chewy and Amazon.
Dental health: Check teeth and gums monthly. Healthy gums are bubblegum pink, not red or pale. Tartar appears as a yellowy-brown buildup along the gum line. Brush with Virbac C.E.T. Enzymatic Cat Toothpaste two to three times per week. If brushing isn't possible, Greenies Feline Dental Treats or a water additive like Oxyfresh Pet Water Additive provide meaningful plaque reduction as an alternative baseline. Vet tip: Dental disease affects over 70% of cats by age three. Starting dental care at any age is better than not starting — but starting young makes it dramatically easier for everyone.
Healthcare Checklist
Vaccinations current? Core vaccines for all cats are rabies and FVRCP (feline viral rhinotracheitis, calicivirus, panleukopenia). Cats with outdoor access or contact with other cats should also be vaccinated for FeLV (feline leukemia virus). Never skip rabies; it's legally required in most US states and many other jurisdictions regardless of indoor/outdoor status.
Parasite prevention current? Monthly preventative coverage for fleas, ticks, and internal parasites should be year-round. Revolution Plus and Bravecto Plus are broad-spectrum prescription options that cover multiple parasite types in a single monthly application. Keep a simple log of application dates — a gap in coverage is when infestations take hold.
Microchipped and registered? A microchip is only useful if the registration is current. If you've moved or changed your phone number since the chip was implanted, update the registry now. You can look up your cat's chip registry through the AAHA Universal Pet Microchip Lookup tool online and update contact information directly. It takes about five minutes.
Home Environment Checklist
Toxic plants removed? Common houseplants toxic to cats include lilies (all parts — potentially fatal in small amounts), pothos, dieffenbachia, sago palm, and oleander. A complete list is maintained by the ASPCA Animal Poison Control Center. If your cat is a chewer, replace household plants with cat-safe alternatives like spider plants, Boston ferns, or catnip.
Litter box ratio correct? One box per cat plus one extra. If you have two cats, you need three boxes minimum. Scoop daily. Full replacement of litter and washing with unscented soap once weekly. Track any changes in output — frequency, consistency, or the presence of blood are all reasons to call a vet promptly.
Enrichment adequate? Does your cat have access to vertical space (a cat tree or wall shelves), a window with something to watch, and at least two interactive play sessions daily? Boredom is a welfare issue for indoor cats and the root cause of many behavioral and health problems. For a detailed guide to play routines and indoor enrichment, see our full guide on cat exercise and indoor enrichment. The complete cat care library covers everything from kitten setup to senior cat needs.
Frequently Asked Questions
How do I know if my cat's food is actually high quality?
Look for: a named animal protein as the first ingredient, an AAFCO statement confirming the food was tested through feeding trials (not just formulated to meet guidelines), and moisture content above 70% for wet food. Avoid foods where the first several ingredients are grains or where protein is primarily from plant sources — cats cannot use plant protein as efficiently as animal protein.
How often should I take a healthy adult cat to the vet?
Once annually for cats under 10, twice yearly for cats 10 and older. Senior cats benefit from bloodwork at least once a year — kidney values, thyroid levels, and blood glucose all shift gradually in ways that aren't visible externally until the condition is advanced. Catching kidney disease at Stage 1 versus Stage 3 makes an enormous difference in both quality of life and treatment cost.
My cat hates being groomed. What do I do?
Start shorter and slower. A 30-second brush session ending with a high-value treat is more productive than a 5-minute battle. Build duration gradually over weeks. Use a soft rubber brush like the Kong Cat ZoomGroom for cats that find metal-bristled brushes unpleasant — many cats tolerate rubber brushes much better. For extremely mat-prone long-haired cats that resist all grooming, professional grooming every 6–8 weeks is a legitimate option.
What household products are toxic to cats?
The major categories: cleaning products containing bleach, ammonia, or phenol (Pine-Sol and similar); essential oils especially tea tree, eucalyptus, and citrus; permethrin (in dog flea products); lilies and several other plants; xylitol (in some human foods and toothpastes); and ibuprofen or acetaminophen, which are acutely toxic to cats even in small amounts. Keep the ASPCA Animal Poison Control number saved: (888) 426-4435.
Final Thoughts
Running through this checklist takes less than 15 minutes once a month. The value isn't in any single check — it's in catching the slow drift before it becomes a crisis. A cat eating slightly less than last month, a coat that's slightly less glossy, nails that are slightly longer than ideal — noticed early, these stay minor. Noticed late, they become emergencies.
