We recently adopted a kitty from a lady working at the local vet. She rescued the mother cat and cared for the kittens, finding homes for the entire litter. Olivia was the last of the lot - she was described as a loner, entertaining herself and not requiring a lot of attention from her litter mates. Here's a video showing her in action. Hope you like it (the background music is from Vivaldi's Four Seasons, by the way).
