I adopted a beautiful cat last week.
My other cat is used to cats, I have always had more than one, but he has seemingly been terrified of the new cat on first sight.
It's more than a bit of hissing. He will hardly come in at all. When he does he growls and hisses ALL the time. He is clearly terrified.
I feel awful as my old cat is unhappy and my new cat must be confused.
Should I return him?
