I have a soft spot in my heart for squirrels right now.
We have a squirrel who lives in the big oak tree in our backyard. Whenever our cat Audrey goes outside for a stroll, the squirrel gets really worked up, chattering and scolding Audrey while jumping from branch to branch. Audrey is cross-eyed (she's part Siamese) so I doubt the squirrel has to worry.
I just found a sweet blog about a squirrel named Scooby Snacks, who was rescued as a little runt. Just check out this photo, then click it to read her story.
I think I spied these on design*sponge a few months ago.
