Congratulations and good luck! (Good luck because you never know what you're going to get. re: animal behavior, human behavior, etc. And also because burn out can strike when it's least expected when you're dealing with animal rescue. Don't be afraid to vent if you need to!)

I'm curious now though... you mentioned that the cats are free roam in the cat room. Doesn't the shelter you work for ever get cats in that don't get along with other cats? What happens to those?
