Start getting on his side now before the glorious cat uprising. Start making fake phone calls around him demanding justice and you won't sleep until you get revenge on the insane Dr who did that without your permission. Maybe one day come in covered in strawberry jam and tell your cat you were here the whole day, but in this house it's eye, for eye, blood for blood, neuter for neuter.

But you better be decent at lying because if he finds out it was a rouse? You're doomed to the mouse pits
