Welcome to the Union of Critters, where the most discerning critters come to unite and plot world domination!
Step 1: Find a critter buddy. It's a union, after all, so you'll need someone to moo-ve with.
Check the critter buddy requirements to see if you and your potential partner are a match made in heaven.
Step 2: Fill out the Union Form, which includes questions like "What's your favorite snack?" and "Are you a morning critter?"
Step 3: Attend the initiation ceremony, where you'll meet the rest of the critters and learn the secrets of the union.
A: Any critter with a pulse (or a decent approximation thereof).
A: No. You're just a pawn in our feline overlords' game of cat and mouse.
