By "Catwalks" I am guessing you mean Cat-tracks, at least that's what I've always heard... But yeah in my experience, this usually happens to me because of a few things:
a) I haven't stretched out properly before riding
b) It's the first day riding in more than 3-4 days
c) my boots are either too tight, too loose, or bindings stance is off
d) it's early season and my legs aren't fully back into it.
Usually D) is the main reason - after about 20+ days into the season this seems to happen to me a lot less. Also as magnetism pointed out, hydration is a big factor on top of these things.
Definitely keep switching between edges, or if possible, try riding switch. Sometimes on a slanted cat-track I'll ride switch to save my ankles from not being able to carve and switch edges.
