You're on to their scheme. Isn't it suspicious that your cat WANTS to got to the vet now? Suddenly there's something to go for.
You notice the way she saunters swiping your keys off the counter only to return after a couple of hours. You had someone look into it and here you were investigating the "South Powhattan Veterinary Club." You walk in the front door "Alright! Where the hell is she?!"
The cat just peers at you from behind the counter. "Excuse me, do you have an appointment?"
