With any luck you will be able to coax that Poor Cat in , and even if you dont want to adopt you can get that poor lost soul to safety , as thats no life for a Cat as a nomad.
Tubby 2 , and Ebony Beau Tubster Angels are there trying to convince that Black Cat that you are one of the Good Humans and will give him/her a Great Furrever Home!!!

I do the same with the Porch Cats and make sure thier back and front yard dishes are always full!!!
