This is a Chia Pet pet costume made by Etsy seller TheHolidayShoppe. Here’s one being modeled by a little chihuahua. I guess that would make him a… Chiauahua Pet? No, no it doesn’t. It makes him a chihuahua wearing a Chia Pet costume. The shop sells small and medium sizes which should fit cats (but NOT Garfield), plus small and medium dog breeds. Just don’t let Fido outside wearing this thing. He’ll blend in with the bushes and you may never find him again!
