Which of your other cats might have an "issue" with the newbie?
So glad your hubby has made these decisions and you let him. lol
I have found that when the NEW kitty is brought in there are kitty tantrums for about a week lots of hissing ect. THEN you will see them all snuggled up together out of nowhere!!! As long as they are all neutered or spayed they get over the tantrum very quickly!!!
