u/Fickle_Tangerine8610

Only recently introduced. 9 week tabby, 13 week white.

It seems a bit aggressive. The occasional hiss/meow. Sometimes it seems like the little guy is trying to get away, but then he does things like at the end of this video where it seems like he wants right back in it.

First door introduced, then crate in same room (temporary only for introduction) and they seem to play a lot through the crate and will even sleep next to each other through the crate sometimes.

I've only ever had older cats who already had established play boundaries so im not sure how to read this. Just want my babies to be happy and safe.
