Why is my older cat eating less after new kitten introduced?
Your older cat is yielding part of his territory, including his food. He allows the kitten to eat his food, but he can’t eat hers without her hissing at him. He senses that she is younger and will become stronger than he is, so he is backing off. Try filling his dish to the brim with lots of dry food. If he doesn’t eat it, there’s no harm done. But if there is plenty in sight, he will probably start eating normally again. It is good that you are petting your older cat a lot, because he will feel left out if you don’t. They should have seperate kitty litter boxes, at least for a few months. That will help your older cat keep his own scent in a spot that is his own. If the kitten tries using it, take her to her own box.
