She has a collar but no tag. My Dad was reluctant in getting her one. He's always the type to be "it'll never happen to us" when it comes to my pets. He kept giving excuses that she didn't go downstairs or she'd know how to get back. We have a rabies tag and a license (though not an id tag yet) for one of ours who goes downstairs regularly which took a lot of fussing from me.

The only thing she has on is a collar, so if anyone picks her up they'll know she belongs to someone but there is no way to identify her. I really wish he had listened to me, and let me get at least some type of tag for her.. because now she might never be found..
