Didn't some guy use his mouth to hold film and do pinholes from inside his mouth? But, thankfully, I don't think anyone has used a non-human animal to do pinhole.
As for the OP's question, I don't see why not. You just have to decide what side you want to put the pinhole on and whether you want a curved film plane or not.

There was one fellow back in the 1980's who actually used a hole between his teeth or holding his lips open just right was able to make photographs with NOTHING but film. Here's another guy; pretty impressive stuff, in my mind:

Yes, I certainly agree with that; the point being though, just about everything has been made into pinhole cameras. For a while, it got downright tiresome. As if the point was to make something into a camera that hadn't been used before. There was a lot of stuff and lots of it was ingenious, but I soon got pretty tired of it. Check out early Pinhole Journals; full of it.
Did you hear about the cat in Seattle, Cooper, whose pet humans attached a digital camera on his collar, on a timer? He's done some great stuff. There's a flickr site which alludes me at the moment, but here's his blog:
By the way, I really appreciate people who build their own cameras out of found materials, rather than buying them. There's nothing wrong with that, either but for me, designing and building the camera is an essential part of the process.
I made a pinhole camera in exactly this way some years ago, using one of Ilford's 17m plastic bulk containers (haven't seen that size for while, is it just 30m thats available now?) and it worked perfectly.
What I liked about it was that the image formed over the whole width of the 35mm strip I'd taped into it, and included the perforations as well. It was good fun. I ended up with roughly 6 inch long contact prints from each exposure, with a very panoramic distorted feel.
We used to play with the Kodak tins in that same fashion at the newspaper I worked at. We used circles cut from print paper for negs and rolled up little cylinders of cardboard and taped it to the the side to make legs so the tin stood up like an alarm clock.
