I recently bought an 8 week old female kitten (belle), she is great, very lovey dovey, about 4 days after we got her we decided to go back and get her brother (archie) from the pet shop, we bought him home and introduced them, they didnt hiss or growl, i think they recognised each other. Archie is more stocky than belle and can easily oush her around.
My question is when they wrestle they bite each other, im not sure how hard, if any of them meows which is rare i will break it up, Is this normal behaviour for them? or should i be worried?

Thankyou in advance

Absolutely normal! Worry if they don't behave like that. (At this young age)
