Sounds like you made the right decision to me. You can always put up some FOUND CAT posters or a newspaper ad if you want.

A responsible owner should have a collar and tag on the pet. I have to admit that I haven't always had tags on my cats. I know that I'm taking a big chance by making that choice. But, you might have the cat checked for a microchip to be safe.

The worst regrets are about things we didn't do. I don't think you should regret this for a minute! Good luck to the kitty - and to those who care enough to save her.
