Desperately need help; new cat attacking my other cat...
This is my first time here.
I recently adopted a young spayed female from the Humane Society; last Saturday, to be exact. I have 4 other cats; 3 females (all spayed) and 1 male (neutered; had adopted him from the Humane Society this past February).
I've kept the new cat, Bitsy, in her own room since getting her.....but gradually over the past few days I've been allowing her out of the room so that she can mix with my other cats. The females have taken to her but she (new cat - she's estimated to be between the age of 1-2 yrs) has a thing for my male. The minute she sees him, she runs for him and voraciously chases him through the house. Now he, Hobee, is a very sociable, docile cat. He is the nicest cat and my other cats loved him instantly. HE is not the problem at all, it's the new cat. She'll see him from across the room and she'll run 90 miles and hour after him, he runs, she follows, until he's almost cornered........and he's growling and hissing. She's relentless. I feel so sorry for him, he looks so dumbfounded. Today I found him hiding in my walkin closet. I think he's starting to become afraid of her.
My fear is that one of them will get real hurt (scratched cornea, etc) or one of them will start spraying (is that possible? neither have before, but I just thought that if one of them feels the other is in their 'territory' that this could start and that would be devastating!).
I feel horrible locking her up all day but I feel equally horrible when he's hiding because of her.
Is this something that will just take time?
She did this the first time I let her out; the minute she saw him, she took off like a lightening bolt after him. She's half the size of him (she's very tiny, at 6.5 lbs, he's 2 yrs old and 12.5 lbs) and obviously too big for her britches.
What on earth can I do to facilitate them getting along, or at least, her stopping this crap of tearing after him and cornering him.
He's never had an issue with her, he doesn't initiate anything. But now when he sees her, he's on edge, watching her like a hawk and then she sees him looking at her and she tears after him.
Do I just let them figure things out on their own?
I did originally put her in her carrier and sit her in the living room so that the other cats could 'sniff her' and she them.....there was no hissing between them through the carrier.
I just don't know what to do here.
Would greatly appreciate any advice.
