Pet rocks are NEVER in a bad mood! They will ALWAYS be there to listen, or just sit quietly with you!
Pet rocks are COMPLETELY safe!! (unless your kid brother throws one at your head)
Pet rocks are SUPER cheap!! A cat or a dog could cost you HUNDREDS of dollars! Out pet rocks are UNDER $10, with FREE shipping!!
Unlike some SUPER GROUCHY pets, rocks will NEVER break your heart by DYING on you! Pet rocks pretty much live FOREVER!
