This is my cat, Baghira -- after the black panther in Rudyard Kipling's The Jungle Books.
She's a marvelous cat, she loves attention, loves to play rough and she even does a trick: she rolls over on command.
The one problem we have at the moment is that she has started to go to the bathroom outside of the cat box. No urine, just solid offerings.
We figure there must be something wrong, like she is feeling unwell, or the other cat, Albion, is mistreating her in some way. There is definitely a different feline dynamic in the house, they are in each other's territory at odd times, and there are more open hostilities than ever before. I wish there were some good way to diagnose the issue, but I'm afraid there is not.
