I am kind of in the same situation, So I thought I would ad my input. I have a beautiful male that has been hanging out at my home. At first I thought he was just a visitor. I do keep putting food out there, so I know the surrounding strays arent hungrey. So the other day I check him for fleas, and so far didnt find any. So I thought for sure he was someones pet. and was here eating the good stuff

But everyday he still is here. So this morning I went out while it was still dark and called, and sure enough he ran out from under my home at 5 am. Okay this has been on going, everytime I see him or call, he is under my home. So i went online and looked at a few lost and found sites, NOthing! I have made the choice to get him in a pet cage tonight and keep him here for a week, and see if someone doesnt come looking. If not he will be ready for adoption in about 10 to 14 days. What other choice do I have?
