Murdercat 

The 3rd cat in any household, completing a kitty cabal, ultimately leading to the death of everyone in your household. A little known ancient designation originating in Egypt in the 1st Kingdom, and was the undoing of more than one Royal Family. The main reason British Royalty has always preferred canine companionship. Rumored to be the most likely cause of death in the case of Cleopatra. However, this was suppressed for centuries by the Meowmiati, a clandestine organization made up of elderly cat ladies, who changed the narrative to blame a serpent, further vilifying the snake.

After all other suspects had been cleared, detectives determined the family unknowingly brought about their own demise by bringing a third feline, a Murdercat, into their home.

Moderats 

Political centrists who take on the political positions and sometimes the physical appearance of rats.

Damn those moderats for endorsing Biden. They're all going to get cabinet positions for which they are unqualified.
