Cat update
My Mom's cat has been spayed and staying with me for the last week. Initially she wasn't very friendly and wasn't eating much. I did buy Feliway and plug one in int he bathroom and that seems to have helped (Thanks Liz!). If she continues to eat and poop, she'll be going home to Mom this weekend. She is still hissing a bit but she is much friendlier than she ever has been so I think between the spaying and the pheromone therapy, we might have saved her from being euthanized for her behavior.
