I feel the same way about Lily. She is so small that I like for her to have a bell on. I use the break away cat collars on her. I don't use it for walking of course, but I do keep an Id tag on it for back up. She got it caught in her mouth once when she and Dixie were playing and it just popped right off! I definitely recommend you try one.
Here is a place I love to get them at. They are satin so their hair does not matte and I love the rhinestones!
