In the top photo- I'd say squirrel. The 4 feet are all group together so that it appears to be hopping rather than walking. I believe rabbits have larger prints for their hind feet.

At the very least it seems to be of the canine family, you can see the claw marks in the tracks(cat's claws are retractable, will usually only be visible when they are running or pouncing)and the heel marks are much smaller than the toe marks. You're right that its not a bear track. Do you have a neighbour with a very large dog, say 90-100lbs or over? I'm not sure of their range, and it would seem unlikely that close to your house but do you have wolves where you live? I've included a link to an animal tracking website, and there is a picture of a dog track in snow towards the bottom of the page, and it looks very similar. You can also search other tracks if you think that its something else, there is a good list. Here is another site that compares a dog's foot to a wolf track: http://wolves.wordpress.com/2006/10/19/comparison-of-wolf-and-dog-tracks/ Is it possible to measure one of the tracks?(if its still there) Here is a link that might be useful: Dog tracks

This is a bit of a late post, but what the heck. About raccoons..... One Thanksgiving we had the gang at our house. My dad, at the early stages of Alzheimer's decided to make his specialty...pumpkin pecan pie. Unfortunately he forgot to add sugar and I don't think he cooked the crust or something. Whatever it was it was sort of funny. Not telling him what he'd done we just ate the other desserts and told him we'd be glad to keep his. We put it outside, disposable tin and all, and the next morning everything was gone! We laughed. Next spring out by our back gardening shed, I spied something shiny and silver. It was the pie plate, pushed out of the raccoon's "house!" We laughed some more!!

Hello again, hello. I sent the photo to an animal tracker that I met up with on the internet last year and he agrees that it is a rabbit. If you look at the last photo (not my pictures, but from a tracking website) you can actually see the 4 little paws together. My photos were taken after the snow was a little melted so they aren't as clear. But it's definitely a bunny. Anita
