So sorry for the loss of Knitty Kitty. I know it hurts, even though you only had her for a short time.
We adopted a kitten that someone abandoned in our neighborhood. Shortly afterwards, we found out that he had feline leukemia, and we had to quarantine him from our other three cats (who never went outside) until they got their leukemia vaccinations. We kept him in our bedroom, with the TV on Animal Planet for him when we weren't home.
He was the sweetest little guy, named Tom. When his quarantine was over, we let him get to know his sister cats, and he fell madly in love with one of them. They played and played, and played until he exhausted himself. We had to have him put down, but he had a nice life for the short time he was with us, and we like to think he died happy.
