I received a call about 9:30 last night from the same people who I had contact with before. They said the cat they thought was mine was outside. I rushed over and the cat was in the front yard.
I was able to get within 5 feet and I do think it is Phil. He was very skittish and didn't hang around for but a moment. I decided it would make it worse If I chased him so I let him be, left some food and a cat carrier. I'm heading over at lunch to talk with the people who's back yard he seams to have made home and let them know what I'm doing.
I also have a coworker with a small animal trap, he's bringing it with him when hew returns from lunch.
Wish me luck!
