I have an 18-month-old DSH male cat, he is mainly white with red shipped tabby markings on his head & upper back. When we found him he was wondering outside, a stray. He (Finn) was about 3 or 4 weeks old, still had blue eyes (for another week), weighed less that 1-lb, and had trouble eating canned cat food. At 18-months Hes long, and slim (8-lbs) with a little head. I've been told that that white cats, as well as red cats tend to be bigger than average. Why isn't he bigger? Was he the runt of his litter? Could his size be the result of poor prenatal care? He eats well, he eats 2 6-oz can of cat food a day & is very active. Will he ever look like an adult cat?
