Some of you may know I've been feeding a feral cat we call New Kid for years. I have heated bowls outside and he lets us know when they need filling. Actually, my cats let me know he's waiting for his food.
I live-trapped him (he will not let us come near him) a few years ago to get him neutered using the TNR (trap neuter release) philosophy. Corey built him an insulated shelter which is placed under our deck. I should have never let him go. But I was trying to be humane. Regretting letting him go, I've tried to live-trap him again several times, but he's too smart to go in it again. Like Corey says, he must be a smart cat to have survived all these years outside.
I took this picture of him today sitting in his heated food bowl waiting for his breakfast.
