I have a 1 yr old cat and a 5 month old puppy. The puppy chases after the cat biting and jumping on him. He seems to take it and doesn't really fight back to hard but just lets her play with him. I think that she is hurting him so make the puppy stop but then when I try to keep them separated he meows at her and then seems like he wants to play with her. He sometimes will jump up on the bed or the couch, cry and then wrap his arms around her and bits her. This make me think that he wants to play with her but they just can't seem to find a happy medium because she is growing so fast and is now bigger than him. I'm afraid to leave them alone in a room together because he doesn't really make her stop and always has to be around her and the puppy doesn't understand that she can't go after him like that all of the time. Does anybody have any thoughts on this or should I just let them go at it and not worry so much?
