How do I know if my cat is obese or just a large breed?

Even genuinely large breeds like Maine Coons and Ragdolls have ideal weight ranges -- a Maine Coon can be healthy at 6-9 kg, but one at 10-11 kg is likely overweight for its frame. The body condition score is more reliable than weight alone: if you cannot easily feel the ribs with light pressure, and there is no visible waist from above, excess weight is likely regardless of breed.

Can obesity cause diabetes in cats?

Yes -- obesity is one of the most significant risk factors for type 2 diabetes mellitus in cats. The good news is that in cats diagnosed with diabetes, weight loss (achieved gradually and safely) sometimes leads to diabetic remission, which is an outcome that makes the effort of weight management very worthwhile.

Is it safe to put an obese cat on a strict diet quickly?

No -- rapid calorie restriction in cats is specifically dangerous because of the risk of hepatic lipidosis, a potentially fatal liver condition that develops when cats stop eating or eat very little. Weight loss in cats must be gradual (typically no faster than 0.5-2% of body weight per week) and should be supervised by a vet.

Does neutering cause cats to become obese?

Neutering reduces metabolic rate and can lower activity levels, which increases the risk of weight gain if food intake is not adjusted. It does not make obesity inevitable -- adjusting portions after neutering and providing adequate enrichment and activity helps prevent it.
