All of my cats wer collars with identification. They are the elastic type that expand so they cannot risk choking to death. I too have had my cats get their teeth stuck intheir collars, usually it were kittens that had just worn a collar for the first time, and they eventually get used to the fact that there is something around their neck and there isn't much they can do about it.

I will be getting my cats tatooed when I have enough money. The thought of microchipping scares me. It's a devil satin thing. And I would rather have my cats heads cut off then go to hell, lol!

Tatooing is fairly common, especially for exotic pets. For cats, they just shave the ear and tatoo the inside. I have also thought of ear tags too.
