The Well Cat Guide — feline health for cat owners, in plain language.

A cat can look settled on a windowsill while small changes are taking place in its daily life. The useful question is often less about whether your cat looks ill and more about what feels different from normal. Perhaps the usual greeting is missing, a favourite perch stays empty, or the litter box needs cleaning more often. Those observations are worth bringing to a veterinarian. This guide helps you describe what you have noticed without trying to name a disease from a few signs.

Regular veterinary visits also matter when everything seems ordinary. The AAHA/AAFP Feline Life Stage Guidelines describe care that changes with a cat’s life stage and lifestyle. A visit is a chance to talk about the cat you live with: its meals, movement, resting places, litter habits and response to other animals. An owner sees the daily pattern; a veterinarian brings an examination and knowledge of feline health. Put those views together by preparing questions before the visit, rather than waiting for a dramatic change to make the questions feel important.

Behaviour belongs in that conversation. The AAFP Feline Behavior Guidelines were written to help veterinary practices include behaviour in feline health care. A cat that avoids company, stops playing or takes a different route around the house may be telling you something through its actions. A page about behaviour can help you notice that change, but it cannot tell you whether discomfort, fear, a change at home or another cause lies behind it. Your cat's usual habits are the starting point. They are not a test that rules illness in or out.

The Well Cat Guide covers signs of illness, common feline conditions, everyday care, veterinary visits and the needs of older cats. It also explains where feline research fits into the picture. The Cornell Feline Health Center describes research, outreach and education as central parts of its work. Start with the topic that matches your question, then follow the related reading when another issue overlaps. The aim is to leave you with clearer observations and better questions for your veterinarian, not a plan for diagnosing or treating a cat on your own.

Start with the change you can describe

If something has changed, write down what you actually saw. A cat leaving food in the bowl is an observation; deciding that it dislikes the food is an explanation. Keep those separate. Note whether the change happens during meals, after activity, near another cat or in a particular room. Include what still seems usual as well. A short, plain account can be more useful than a long list of possible diseases found while reading.

You do not need to watch your cat continuously or turn the house into a testing space. Familiar moments are enough to help you remember its pattern: filling the water bowl, cleaning the litter box, offering a game or settling down in the evening. If a concern is urgent, contact a veterinarian before spending time making notes. Reading is something to do alongside veterinary care, never a reason to put that care off.

Use everyday care as a conversation starter

Questions about food, litter and play are welcome questions for a veterinary visit. Bring a description of what your cat eats and how meals work at home. Explain where the litter boxes sit, whether another cat blocks the route, and whether jumping or climbing seems different. The pages in the everyday-care group help you think through those ordinary details. They offer a way to organise the conversation rather than a promise that changing a bowl or a toy will fix a health problem.

Choose reading that fits your household. Someone living with an older cat may begin with comfort and movement, while someone welcoming a young cat may begin with indoor spaces and clinic visits. A home with several cats may need to think about access to quiet resting places as well as access to food and litter. There is no need to read the entire guide in sequence. Return to a page when its question becomes relevant.

Take the question back to your veterinarian

Before an appointment, make a brief list of the concerns you most want to discuss. Put a recent change near the top. If a page contains an unfamiliar word, copy the word into your notes and ask what it means for your cat. If a recommendation seems hard to carry out at home, explain the practical difficulty. A clear question about the cat's routine gives the clinic team something concrete to respond to.

When reading about research, keep the difference between a study and an individual cat in mind. Research asks questions about groups, biological processes and patterns. Your veterinarian assesses the animal in front of them. A finding can be interesting without being a diagnosis for your companion. Use the topic index below to find a useful starting point, and use the reading list when you want a fuller explanation of how the subjects connect.
