From Kitchener, Ontario

We have had 'possums in our back yard for a few years now.

They are the ugliest things I have ever seen and do nothing but hiss and spit at you. They only antagonize our dogs.

We found another one today and our one dog (shihtzu) is still looking for it. I am afraid they might be rabid so we send him off to 'possum heaven and hope he has no relatives that will come to look for him.

I don't want to be mean, but I can't afford a vet bill if it by chance bites one of my dogs.

By the way we live in the city but along a railroad track.

Can anybody tell me how to keep them away?
