I first became a Cat Mom when I was chosen by a feral kitten over 20 years ago, and don't plan to be without at least one, preferably three, ever! They are such a joy to me. To help you find out if someone is missing a treasured furbaby you could take her to a vet or shelter to have her scanned (it's free) for an ID chip; if she has one it will connect to her human family, and if she doesn't, you will feel more secure about adopting her. An old pillowcase makes a good temporary cat carrier for the visit. If you do get to keep her, know that an indoor cat is safer and lives longer than one that goes outside.
