Great concept, but...
I've been playing this occasionally with friends, and the idea is brilliant - playing as cats (with every stereotype from moggy to inbred pedigree) is brilliant fun. The problem is... Well, the rules kinda suck.
They just about hold together for general gameplay, but you quickly hit situations that make the rules seem unfinished - you can spend magic points, but there's no mention of how you recover them. You can give other characters traits as rewards, but can't gain them otherwise, and so on - there's a few typos as well. If this was a first draft, it'd be understandable, but billing it as 'revised' when there are both rules and basic formatting errors is a bit off.
The setting is great, and I'd love to give the author money for an Actually Really Revised edition, but as it stands you'd be better off nicking the campaign idea and using a rules-light generic system like Fate Accelerated.
