We have had our cat, Harley, for several months now. He is a year old. We got him from the Humane society and they told us that Harley had a friend with him at some point and that he was very good with other cats. Yesterday, we got another cat from the Humane society and we have introduced them slowly at small increments of time. Harley is trying very hard to make friends. He even gave the new cat a bath. The new cat is 4 months old and he will play for a while and then he'll hiss and growl. Is this something that we should worry about right now or could they develop a friendship.
