My cats are microchipped, and Couver will be in a week when he is neutered. There is no reason not to do it. I feel that any extra way for him to be recovered is a plus. I know the feeling of losing an animal, and I do not want to have to deal with that. Couver has tags, will have a microchip and be registered with my town. This way I have all my bases covered, and will not hate myself if he manages to get away.
He is my child, and I will do anything to keep him safe.
