Hello a basic history. my cat should be 6.25kg I have 4 other cats, but one is gaining weight which I don’t want. I have Bubbles age 13 (5.3kg), Taffy age 12 (6kg) Bollo age 12 (nearing 6.75kg) all from same parents. Buttons age 10, 5.75kg and Nala age 6 (about 4.25kg) Bubbles was 6.5kg why has bubbles lost weight? He simply didn’t eat cat food except 1 type, dry purina pro plan junior., then, he started to lose weight. So, we took him to the vets and they did many tests, found nothing but he was getting stressed and started to pull his fur out. Found out about 18months later that purina changed the formula to the cat food, that bubbles didn’t like. So he refused to eat. All he eat was left over meat from our dinners. we switched over to purina one, where he nibbles at the food, but not much. I have decided to make him food from home, he has several good meals out of each batch. It has vetiq nutri-vit plus so he gets what he needs. However bollo has realised bubbles gets something different and eats it too, making him fat. bubbles weight loss has stopped, he is very skinny as he is a big built cat. His fur has grown back. The vet has given us many foods but bubbles isn’t interested. so, I am after something that I can put in a syringe, where I can get a liquid extremely high calorie supplement. does anyone have any suggestions? Oh, bubbles only has 10% of his tail.
