I recently adopted a male kitten Toby(neutered) about 3 weeks ago.(He’s 3 months) I decided to adopt another kitten so he wouldn’t be lonely. I adopted a female kitten, Mia, that is 2 months old.(spayed)I brought her home 4 days ago in which they’ve been in separated rooms. When I let Mia come out and play there’s no hissing or fuzzy tails, she’s really friendly but Toby grabs her and bites her and he won’t leave her alone. I’ve told him many different ways to stop but he won’t listen. Although Mia doesn’t seem to be scared of him. They eat together but after he won’t stop chasing her and biting her. She cries out and I get him off but I don’t know if Toby means to hurt her or if he’s just trying to play. Please help!
