We have a 3 year old Russian Blue female. She has always had a bit of an attitude...stand-off-ish, and only wanting attention on her terms. I know a lot of cats can be that way. After thinking long and hard about it, we decided to bring home a new kitten, knowing Lexy might not be too receptive to the idea. We really under-estimated her reaction. She is SO mad and SO stressed out that she's even attacking us. I'm still keeping the kitties apart, they haven't been together yet...only sounds and scents. I'm afraid Lexy may even try to kill him. I couldn't stand seeing her so upset so I took her to the vet today and he started her on some MEGESTROL to help with her anxiety. Has anyone here used this before, and if so, did it help?
