We just got our second kitten Lucky Boots last week and after a trip to the vet today we finally let them have some time together. Well our original kitten Sushi seems to possibly be bullying the other kitten maybe? He follows him around and pounces on his back a lot and bites at the others neck and sometimes flips him over and bites at him. I don’t know if it’s playing or if he’s being mean. There’s no hissing or tail lashing or ears back or other signs of him being upset but I’m a bit worried. If it helps Sushi is 15 weeks old and Lucky Boots is probably some where around 8 weeks old.
