Weight, appetite and water: the three things worth tracking
Most of what goes wrong with a cat's health announces itself quietly, in numbers you can actually watch at home. Cornell's Feline Health Center flags obesity as the most common nutrition-related problem in cats and the gateway to arthritis and diabetes, and it recommends a body condition score rather than guesswork: a 9-point scale where 5 is ideal — ribs palpable under a slight fat covering, a visible waist behind the ribs, and only a minimal fat pad on the belly. A cat scoring 1 has no palpable fat at all and visible bone; a cat scoring 9 has ribs you cannot feel. If you are unsure, ask your vet to set a target weight and check it at each visit.
Cornell also notes that cats vary enormously in how much food they need, so a bag's feeding guide is a starting point, not an instruction. Appetite and water are the two easiest early signals:
| What you are seeing | Why it matters | Next step |
|---|---|---|
| A cat that refuses food and is losing weight | Cornell warns a cat that stops eating can develop serious medical problems, and losing weight makes it worse | Book a vet visit rather than trying a different food first |
| Weight creeping up over months | Obesity is the most common nutrition problem and a risk factor for arthritis and diabetes | Ask your vet for an ideal weight, then measure meals instead of free-feeding |
| Eating fine but the coat, litter or energy changes | Cats adapt to some discomfort rather than showing pain | Mention the change at the next check; earlier detection is the point of senior-stage monitoring |
| A sudden avoidance of the litter box | Tray avoidance can be stress, but it can also be pain — a cat that associates the tray with discomfort will look for somewhere else | If it starts suddenly, treat it as a health question before a training one |
Two safety basics round out this category. Supplements are not a DIY fix — Cornell advises against giving vitamins or minerals without a vet's approval, and a cat that refuses food is a vet case rather than a food case. And because cats hide discomfort, the annual check-up is doing more work than it looks: it is where weight trends, teeth and a physical exam catch things the owner cannot see at home.
