I have three cats, tortie, black/white and a tabby. My tabby is kind of big then the other two. He gets fed when the other cats get fed. He is a male, so I think tabbies can be big and overweight. It all depends on the cat and the body of the cat. I do see lots of overweight cats at my shelter. I can't really answer all your question. Tabbies are prone to being overweight, usually the males.
