Ok I just was wondering if you guys could help me a bit. I have a kitty about 4 months old now and she seems a little skinny to me. Her hip bones and ribs are more prominent than I am comfortable with. She has been to the vet many times and the vet says she is perfectly healthy but I am still worried. I am feeding her wet and dry mixed together, both kitten formulas. She never eats it all but seems to have quite an appetite. I keep trying to get her to eat more, Ive tried different flavors to see if she just didn't like it that much but I am giving her the one she eats the most of. I am feeding Science diet wet and Purina Kitten dry because this is all she will eat. She keeps getting bigger but staying skinny, is this just the way she is growing and will eventually fatten up? Is there any way I can fatten her up, make her eat more, or anything? Or am I just being a worrywart?
