Pet of the Month: Weasoo and Larry! 🐾

Meet our favorite friend visiting Lilac Car Wash

Weasoo and Larry

Weasoo and Larry

Owned by Todd and Korinna

Say hello to Weasoo and Larry! They were both so excited to see another ferret, Lokii, as the September pet of the month, and are honored to join the club. They’re best buds and partners in crime, and are always on the lookout for something new to hide under the couch; their favorite place to stash their treasures.

Species:Ferret
Fun Fact:Ferrets sleep on average about 18 hours a day!
