She ran down into the basement yesterday when I cleaned her room (she doesn't like the vacuum cleaner) and stayed there. When I was doing my night time routine and cleaning out the litter boxes, she scampered out of her carrier and ran around as though she was disoriented. I watched her for a few seconds, then she ran to a corner of the basement and peed on the cement floor. There were 8 litter boxes right there that she could've used. Then she vomited just a drop. I don't know what to make of it. She was fine after that and slept upstairs in her room. She didn't get up as many times for water at the faucet, just 3 times last night, and she slept w/me for a little while. She seems to be ok this morning. Sigh. She sure is puzzling me.
