Hey, i am new to the site and would like to ask a question.... I have 4 cats. Mummy cat is approx 3.5yrs and her 3 kittens are 10months. 1 girl and 2 boys all of whom have been neutered. They weigh between 6-8lbs but one of the male kittens is noticably skinny, he is 7.6lbs when i hold him on the scales. I can feel all his bones through his fur. They all seem to eat fine but he is always asking for food. I have recently had them all dewormed but can a treatment not be succesful or could it be something else that is making him look/feel skinny?
