petsmart.com has kitty collars, on which they embroider kitty's name and your phone number (I think they are 8 bucks). I am planning on convincing Sammy and Sophie to wear them in hopes of avoiding another great outdoor adventure: https://www.catforum.com/viewtopic.php?t ... highlight=
Thanks to all of you for the suggestions and help last time--and maybe this will help a few others avoid my worries.
I have heard that instead of putting your pet's name on a collar, you should put your own. If someone wants to take your pet and keep it, knowing it's name might help them entice the animal into their home, or to trust them.
