I still don't get it...

So, we had that conversation I was planning on...  Nothing definite decided yet, except that she wants a divorce ASAP (she wants to file as early as next week), she's planning on moving out (but she hopes to stay until next summer, so she can buy some furniture and save up for a down payment on a townhome or a security deposit for an apartment), and both of us want what's best for the kids.

Speaking of which, she did mention (for the first time, ever) that she's enjoyed watching me get more involved with the kids over the last few months, and how she appreciates the extra housework I've been doing.  But then complained about how I don't understand her (how can I, if she never talks to me about anything important?), and the lack of trust, respect, and communication between us (same song, second verse).

Urgh.  I digress.

So, she wants to get a divorce, and she wants to move out.  However, yesterday evening, she tells me...  "I was thinking about Christmas presents for the kids, and about how they're both still kind of sad about the cat dying.  I know I've been enjoying not having to clean a litter box, but what if we got a couple of kittens for them for Christmas?  I know you took caught all those mice, but I don't like the idea of them coming back next year.  It was nice when we had Rascal around to catch them.  Oh!  We could even do classic thing with boxes with holes in the sides and a big bow on top!"

Wait...  What?  I was dumbfounded.  What's going to happen to these cats when she leaves?  Is she going to take them with her? I won't be to afford to take care of them.  I don't even really want more pets right now.  If she's planning on leaving, why is she so worried about mice coming back next fall?

I just don't get it.  Am I missing something here?  I think I need to have another talk with her.
