I have had my cat Daisy and her (half) sister Lily for just over a year. They are 5 years old. When they came to me, Daisy was a little overweight, weighing in at 4.5kg... she is quite big anyway and the vet said that the weight classified her as overweight but not obese.
Anyway, we moved her onto set meals, weighed out throughout the day (no free feeding) and supervised so that she did not eat Lily's food. When she next went back, she had gained 100g...!
She then developed anemia due to fleas (they were being treated, but the vet thinks that one of the fleas had some bacteria that causes anemia... I didn't just leave them to suck all her blood!) but it caused her to slim down and she was about 4.3kg. She looked a lot better, had some shape in her waist and hips.
But the last few months she has shot up to 4.7kg, and is starting to look really fat.
She has had repeated urinary tract infections, which have been treated with antibiotics. I don't know if it is linked. However her problem is that she cannot stop eating. Literally, she will eat anything - muffins cooling on a rack on top of the fridge, crisps, bread, tomato sauce, sweetcorn, cheese, mayonnaise, cakes, scones, chicken and fish... anything. And she will literally strike like a snake to steal food from our plates. We rinse out plates and pans now to try and avoid her licking them, but she will fish out food that is floating in a pan that is soaking. This morning I caught her licking the OIL out of a pan my partner left out this morning... and it had had a fair bit in. I can't bear to think of that fat clogging her up her little catty arteries. On two occasions in the last two days neighbours have caught her ripping open left out bin bags and eating whatever she finds inside, and she cries at neighbours back doors for food.
I don't know what to do with her. She is permanently hungry, despite having been wormed. She has never been a stray, so she has never developed the "this could be my last meal ever" mentality. Lily does not seem bothered by food at all, and the various rescues my family have had over the years never have either. I don't know what to do and she is just continually gaining weight. Any food makes her like this
regardless of how much she has eaten.
Sorry to ramble... has anyone else had a problem like this?
