2 cats both about 8. I've had 1 8yrs & the other for 9 1/2 mo and she lives under my bed and will not come out?

Re-home one of them.

A couple things come to mind -- (either, both, or none is possible). ;)

1. The older cat has let it be known that "you" and/or the dwelling is her (his?) place and the kitten is not welcome. So, the kitten has found staying under the bed, out of the way, is safest. Eventually, maybe they will work it out & peacefully co-exist. The kitten may, suddenly, get tired of living under the bed & venture out, come what may.

2. This sounds crazy, but, here, it's a proven fact. My cats get belligerent after eating dry commercial cat food for a few weeks. I was switching them back & forth between home cooking and dry commercial cat foods for over 5 years. Sometimes, they would just cross paths and hiss, howl, rumble! Terrible fights! Then I started noticing the pattern -- dry foods (Meow Mix, Friskies types) = fighting. Home cooking = no fighting. very loving towards each other, sleeping together, cleaning each other. (Commercial dry foods will dehydrate them -- and they can't take in enough water, it seems, to counteract the dehydration. Dehydration, even as in humans, makes them belligerent.) So, your one cat -- if you feed it commercial dry cat food -- has had 9+ years of the food [maybe] and is ready to fight!! ...with anything crossing it's path - except you. So, you might try making your own cat food and see if, in the following month, the 2 don't start becoming friends. Can't hurt to try. [I have made a commitment to feed my cats only homemade food, as best I can, because it stops the fighting and they are so much healthier for it.]

Good luck. I know it's a tough situation.

this may sound silly, but if you have a friend who has a cat-friendly dog, bring the dog over for a couple of days. Your first cat will probably find that the new cat is MUCH less objectionable than a dog.

Talk to your vet. You might be able to put Cat #1 on a mild tranquilizer for a little while until it can get used to the other. Are both cats fixed? That might help, too.

Or.. this is a REALLY different suggestion, but I've worked with Jacquelin Smith, an animal communicator, and she has helped resolve several behavior problems with my cats. She might be able to tell you what's bugging your first kitty, and whether this can be resolved. (I know this sounds totally 'out there,' but when she first worked with my dog--a back problem the vets couldn't diagnose) she told me a couple of things that NO other human knew... but my dog did.)

Good luck.

I think the oldest cat is obviously feeling a bit jealous it is probably the sort of cat that is better of being an only cat . but then i feel your pain to take those other cats back ! take the cat out of your room and then close the door so i doesnt go back under the bed.

maybe she is just too scared and probably its beuz of a new family or the other cats.if u feel that u can help her from trying to get her from under your bed then u can try step by step

you can take him/her out and let the other cat come in and start to play but if that cat doesn't react right grab the other cat and take him out of that room.another thing u can do is lock ur door and show the cat that she is protected by u and nothing can harm her/him.maybe u can also try to cover the sides of ur bed and take the cat out so it has no choice but to stay out from under the bed.i hope i helped and try to right back if any of this works.hope i helped

Your old cat has already give you the answer...the old cat wants its territory back. The kitten must go.

You need to take her to the vet.Thats not normal.shes had more than enough time to get use to liveing with you even if theres a cat there that she fights with she should still be comeing out.Shes probley sick.
