My new male kitten is trying to get milk from my one year old spayed female. He sucks on her little nipples and kneads her stomach as if he is getting milk. She lets him do this and cleans him all the time. Could he be getting milk? Does he think she is his mom? Does she think he is her baby? It is weird when they are not doing this she is chasing him all around the house and pinning him to the ground and biting him until he cries or until I seperate them. Does anyone know what might be going on here?
