Newest recruit in the Tiger Army

What better place to introduce the newest (and more than likely final) member of my household's Tiger Army. Callisto came to me from a friend that is moving to Washington state. She had just recently adopted him, given him all his shots, and had him "fixed". Unfortunately, the cats she already owned basically turned on him regularly, and no matter how he and my friend tried they would not be friendly to him. They are older cats and set in their ways, not willing to bend to the playful, rambunctious ways of a young cat, and my friend did not want to transport him across the U.S. for him to be treated the same way in another new house. I figured that what he needed was a home with younger cats that had no problem being chased and pounced on, and giving the same in return. With that, I offered to see if he would get along with Mr. Tilman and Bathseba, and so far, with a scuffle here and there, they are getting along great.
