Smudge is definitely the oddest cat I've ever lived with and there have been a few over the years. We had the perfect conditions on the river for skating and a bit of hockey. It had rained buckets and then flash froze on top of the already thick ice on the river so no snow removal and no flooding, just perfect skating ice as far as you could see.
So we run out there one evening before dinner and start hitting the tennis ball around and skating back and forth and the dog comes out but won't go near the ice since it is super slippery. Our older cat Baxter checks us out from the shore and then wanders off. Not Smudge, he is out on the ice and following us around and then starts chasing across the ice everytime someone shoots the ball! It's a good thing he has claws because he went skidding a few times but managed to recover fairly quickly. It must have been so crazy cold on his paws! His tail was puffed up to twice it's size so I imagine he was pretty chilly but he would not leave the ice until we did. Crazy cat!
