Indoor cats often gain weight when calories exceed activity — especially after neutering or when food is always available.
Weight loss should be gradual (about 1% body weight per week) under vet guidance to avoid hepatic lipidosis in cats.
Is my cat overweight?
You should feel ribs with light pressure, see a waist from above, and notice a slight abdominal tuck from the side. If the belly drags or ribs are hard to find, ask your vet for a body condition score.
Steps that work for most households
Small changes compound over months:
- Measure meals with a scale — don't free-feed
- Switch to a vet-recommended weight-management formula
- Increase play: wand toys, puzzle feeders, short sessions 2–3× daily
- Limit treats to <10% of daily calories
- Weigh monthly and track trends, not single readings
Common questions
- Can I put my cat on a crash diet?
- No. Rapid weight loss in cats can trigger serious liver disease. Always follow a vet-approved calorie target.
