I have a 10 week old male kitten and 6 year old female cat. He loves to play with her, but all she does is growl and sometimes get up and hiss at him...I'm sure they're playing, but they do worry me because I don't want either one of them to get hurt. They seem to be playing pretty rough. Should I be concerned? Should I just let them play it out, or break them up? When the (much bigger) female gets to growling a lot, I usually squirt them with a bottle, is that a bad thing?
I brought the kitten home almost 4 weeks ago now...what do you think?
