I adopted a kitten from a shelter about a month ago, and she's always hungry! She cries for food, perpetually, and devours whatever I give her. If I'm not home when she's hungry, she steals food. For example, I had a pack of blueberry muffins on the counter, and when I came home yesterday she had gotten them open and eaten two entire muffins. Despite this, she's very small- around five and a half pounds when we got her spayed about 2 weeks ago. I feed wet food (wellness core kitten and blue wilderness kitten) basically as often as she cries for it, and there is always wellness core dry (adult) available for her to eat (I have an adult tom cat as well- I can't leave the dry kitten food down all the time because he eats it and consequently put on some weight.) She's apparently a normal healthy weight for her size, the vet says she's "petite" and we have dewormed her twice. Is this normal? Should I feed her as often as she wants?
