Why Weight Management Matters for Cats
- Health Risks → Overweight cats are more likely to suffer from diabetes, arthritis, and urinary issues.
- Shorter Lifespan → Research shows obesity can shorten a cat’s life by up to 2 years.
- Better Quality of Life → A healthy cat has more energy, improved mobility, and a playful mood.
Signs Your Cat is Overweight
Before switching to a weight-loss diet, check whether your cat really needs it.
- Visible Belly Pouch → Cats should have a slight tuck at the waist, not a sagging belly.
- Difficulty Grooming → Overweight cats struggle to clean their back and tail.
- Less Active → If your cat sleeps more and plays less, weight may be a factor.
- No Rib Definition → You should be able to feel (but not see) your cat’s ribs.
💡 If unsure, ask your vet to do a Body Condition Score (BCS) check.
