You have a wonderful cat my friend. I think the cold will take care of these guys sooner than anything else. Our house is kind of wild and we still have strays showing up at the door. There is a studio apartment building across the street and the tenants come and feed leave cat food and tuna in front of our door. I can't stand it. Those cats are experts in hunting pigeons. I don't know why people keep feeding them. It's like they want the cats to all turn out like Garfield.
