One of our cats is significantly overweight. We've had cats all our lives and never had one who weighed this much. She was a rescue and we've had her for 18 months. She weighed 5.9 kg when we got her and she shot up to 6.5 kg within six months.
Despite seeing the vet for advice and buying Purina weight management cat food (as the vet recommended) Emerald has not lost any weight at all.
She is not taking the other cat's food. We observe all feeds for both of them. She isn't keen on exercise - we got toys which she's supposed to jump up and whack, but the other cat plays with them and she isn't interested.
Her daily amount of food has gone down steadily (on the vet's advice) and we're just stuck now. Nothing is working.
Blood tests show nothing abnormal. No diabetes, no thyroid problems.
Does anyone have any advice?
