Our existing cat, Stella, apparently was lonely and needed another cat to play with. I guess my 2 dogs weren't company enough. Anyway, we're back up to 4 quadrupeds in the house. (An older cat of ours died a few months back.)
So the new cat is Stella's Christmas present. But Stella hasn't shown much enthusiasm for her new friend. Mostly she has stared and hissed.
Well, such are the ways that cats make friends.
First they hiss, and later they purr to make amends.
