My older cat (almost 5) is having trouble adjusting to my new kitten. She's 6 months old, and very affectionate; I'm already in love with her. However, my older cat is hissing and trying to bite me whenever she's near.
I'm keeping her in a cage at night (while I sleep), and letting her out for a few hours at a time. Initially, my older cat was avoiding her and not approaching her, but lately he's gotten more aggressive...and I'm really worried about her, because he's 3 times the size of her!
What can I do to keep the peace? She arrived yesterday, and today has been a big long fight (between me and him.) I haven't yelled at him, but I've been trying to give him affection whenever I can, and he keeps trying to bite me.
