Tinkerbelle was running with a group of cats that an old lady had collected without neutering any....they had grown into quite a feral colony just a few streets away from us. Simba brought the pregnant tiny cat home one night....too young to have kittens I thought, only to be told eventually that this was her second lot! She wouldn't stay in our house, being partly feral, and it was a few weeks before this old lady called me to say she had found the kittens, now about 6 weeks old. They were all found homes and we trapped the colony and had them neutered. Tinkerbelle knew she could get food if she followed Simba and eventually stayed with us. It took us some time to tame her. We estimate she must be at least the same age as Simba, but she is lively and fit and helps herself to the toys in the toybox and will play on her own for hours with toy mice and balls.
