Hi there! postcard

A friend & I found this kitty guy a week ago, just around the corner from my house. He was sitting on some scaffolding where some remodeling was being done. Not only was he not afraid, but we called "kitty, kitty" and he leaped off the scaffolding and came running. We were trying to decide what to do and I said I'd go get a carrier. I sort of ran to make time and he chased me down the street. So I picked him up and carried him to my front yard, where he patiently sat while I got a carrier. He is still here. I put up signs, but I really think he was dumped. Who would let a little one like this roam? I took him to the vet & he tested neg. for feline AIDs and leukemia, but the vet said don't let him interact with Bubba & Missy for two weeks.
