I think the cat board could work if the cat head was at the tail, kinda like a swallow tail. I would like to try and ride them for shits and giggles, but if they were for my wall I wouldn't want to put any scratches on them.
The shape of the cat board looks great other than the ears. Depending on how much rise the ears have they're probably a nonissue, kind of like the deck you can your own nose on. The SB boards just look like a joke to me, especially when you look at the price they want and their belief they're building snowboard art.
