I admire you for trying. I caved in quickly years ago when I had a rescue for 2 weeks. She was a pretty little white with bits of orange long hair feral kitten, about 6 months. She was social with people and tolerant of Grasshopper, but Grasshopper developed some pretty wierd behavior. And the kitten, Monkey, would pee everywhere. It was almost impossible for me to train her to house rules, so she was adopted by someone else, and I have never really tried again. Depending on our living arangement when Grasshopper goes to Rainbow Bridge, I plan on making sure I adopt two together, at least. Although where we hope to be before her time is here, there are lots of outdoor cats, and I will probably be TNRing a lot of them, so may find my feline housemates there. It is sad about Ti and Miley, but they have personalities, also, and like people, some just don't "connect". I think you've done a wonderful job.
