Maxx seems to be okay since her punishment of being in the bathroom, although it's only been a day. Yes, she was in there less than a day. As far as the pooping everywhere, she was not squatting or trying to cover it up at all...very strange! She hasn't done it since. I have not moved or changed her litter. The only thing I have changed was her kibble, which I have since changed back and may take a couple of days to work through her system. If she continues to exhibit strange behaviour over the weekend, I will be taking her to a different vet to get another opinion. She seems to be using her box now, and I hope this problem is now resolved.
