I feed several feral cats... I have 1 momma and kittens in my garage with a heater & another feral on the side of my house in a cooler with heating pad. I have been feeding another feral in the woods near my house for a couple of months now and now he has decided to come in my backyard. He runs when I get close but knows the sound of my voice. Only problem is that I have a Rottweiler who goes in the yard to pee/poop and I don't want him to see the cat. We tried trapping the cat but of course he was too smart to go in the trap even with tuna in it. We put a styrophome house with hay in it but he never want in.. What can we do? He seems to be making it through the winter ok since We are in CT & just had a blizzard. Any advice is appreciated. Thank you!
