I'm sorry to hear that. We have had cats for a long time and now having to put down one of the best cats we've had. She had seven kittens and as she was so young, she ended up having emergency surgery. The very next day she was taking care of her kittens as if nothing had happened. We gave four up to adoption. We lost one of her litter to cancer, and now she has lung cancer. This is going to be tough.
