Spring and summer are just around the corner here in the states (thank goodness!) and that means Tiger and Lily will be spending more and more time outside. Because we don't want our neighbors (or strangers for that matter) to think there are stray cats around, we'd like to get collars for the cats. I'm just terrified to put collars on them because I've heard the horror stories, and my little girls do all the things cats do - climb trees, crawl through thick brush, walk along tall fences, etc. - and so I want to get them break-away collars. But I want to get a good brand that breaks away very easily. I'd rather lose a collar than cause harm or worse to Tiger or Lily. Any suggestions?
