That's really funny about your cat peeing into your ex's shoes!! I've never had a cat, but I've heard they can be quite animated!!

I think your phal will be fine - just take extra care not to bang it/move it/tip it anymore since it just fell - a little drop isn't the end of the world (imagine if kitty had decided to chew on it!) Its important to let the plant settle back into its pot though, so if you can, but it somewhere it won't get knocked over by a human or a feline :-)
