Wall climbing skill like spider

[Phreag]

Coud it be possible that a pet with the climb skill can just climb vertically on a wall when you ride it?

I believe the action of climbing should deplete the hunger of a pet at twice the rate of riding the pet on the ground (flat surface), but this is just me.

It seems that riding something like a Spider (which would likely be given the climb skill) would be at a huge advantage otherwise if the Hunger wasn't effected anymore than say another player's Wolf Pet who doesn't climb.
