While I was cycling along a road in suburban Edinburgh, a rat decided it would be a good idea to run across the road from a garden towards the park on the other side. The obvious route was through my front wheel rather than, say, waiting a couple of seconds and strolling across the otherwise-abandoned road. I'm convinced that it did about 1.5 circuits trapped in the spokes before being flipped out at the top (gaining decent altitude in the process) and scampering off, seemingly unharmed. [I'm well aware it's unlikely it did more than half a loop, since I didn't go over the handlebars. Maybe time did that slowing down thing when you are sure you're about to crash.]
I also had a small bird fly out of a hedge just as I was passing. It hit my rear wheel and was pinged forward past me before bouncing up the road. It didn't look very alive after that.
Lastly, I (got) hit (by) a bird while moving in excess of R17* along the Solar System Way in York. It decided that the safest way to negotiate a cyclist was to fly directly into his thigh. I think it was alright, but probably had a bit of a headache.
* I don't know what that actually means, or if I got it right, but I'm trying to fit in. I was going pretty fast, anyway.
