Is it normal for my cat to be this angry?
We adopted a kitten from the pound yesterday, and my almost 2 year old cat is not taking it well. He has spent the last 24 hours growling, hissing, swatting, and swishing his tail, even towards me. Earlier on today, he finally began playing with the kitten, and then they went back to hissing, then playing, and now they're sleeping.
Is it normal for him to be this pissed off? Will he calm down or should I bring the kitten back?
