I would say anything that your veterinarian offers will be safe, for the most part. The only drawback to the collars are that cats are explorers, and they are prone to getting the collar hung up. If you do go with the collar make sure it’s a “break-away type”. Milo the Magnificent is an awesome name. Our cats are Bela Lugosi, because he is huge with long fangs, and our little kitty’s name is Lily Toes, because she is a little prancer. Cats are awesome, and I’m sure Milo the Magnificent will be the happiest cat, living at his granny’s.
