I know. If you hate the cat posts, you can skip this one.
We've now had Trillian for almost four months and we've learned the hard way that we can't let Xena interact with her at all. On the few occasions when Xena has gotten loose, she's swiftly hunted down the kitten and we've had to run to the source of the shrieking to rescue her.
Trillian's timidity is part of the problem. She runs from Xena and freaks out when she gets close, so it makes Xena think she's onto something with her attack mode. It doesn't help that Trillian is half Xena's size or maybe even smaller than that. It's just bad all the way around.
Thus, we do daily prisoner exchanges between our bedroom and the rest of the house. Trillian sleeps with me all night and when I get up, I put Xena in the bedroom with my husband and let Trillian run free with the other cats. The peripheral cat characters in this drama, Velvet and Velcro, get along with anyone. In fact, Velvet loves to play with either Trillian or Xena.
Trillian really loves to hang out in the recording studio with us. I think it's because it's the only part of the house where she knows Xena never goes.
I've never had this problem introducing a cat before and I don't know where to go from here. I've tried Feliway. I've tried putting Trillian (or Xena) in a crate in the middle of the living room so they can get used to each other. Nothing has made a difference.
This cat situation is also costly. I have to maintain a separate cat box in our bedroom (yuck). We're planning a trip to Nashville this spring and I think were going to end up boarding either Xena or Trillian so that we don't have to make our cat-sitter risk an incident between the two of them. (We'll also have to board Velcro because she gets twice-daily pills.)
The whole problem is so annoying that if I weren't so level-headed, I'd be tempted to seek out a "cat whisperer" to tell Xena not to be such a beyotch. As it is, I guess I'll have to be patient and hope that Xena gets mellower or Trillian gets braver over time.
