Well, oddly enough my guinea pig and dog seem to like eachother. So, that's atleast another animal contact (and I know, I want another guinea pig ;p). I also often take her out of her cage, and she's sitting on my shoulder, under my beard or hiding behind my hair.
Here are the pics, I'll just post the links, otherwise I might fill up this page too much.

I'm not a good photographer. And mind the quality aswell, had to use my phone!
EDIT: (I have to say, the cage looks rather small on the first picture, but it surely isn't)
