I decided this was a good idea:
Why? I don't know. I had been away from kitty for a few nights and felt bad, and thought maybe she'd get along with Boyfriend's kittens.
Right away, I should have known better.
Anyway, I got her in the car for the short 20 minute ride.
Yep, she threw up at approximately minute 18 of 20. And the way home the next day? Puked her little kitty guts out again (whilst jumping from the back seat to the front, to make sure she got the whole interior).
If anyone needs me, I'll be cleaning out my car and looking up car sear covers on amazon. Sigh.
