In this colorful MUTTS Shelter Stories comic, we meet guinea pigs Scratch and Sniff. Scratch says, "You know, there's not only cats and dogs at your local shelter. There could be bunnies or parrots or hamsters or ferrets or guinea pigs!"
While Scratch is talking, Sniff keeps interrupting and interjecting "Guinea pigs!" as Scratch names off the different animals.
Once Scratch finishes, he tells Sniff, "I was saving the best for last." Sniff replies, "Oh."
