[Serious] Why can't foids be bred like pets and live to serve us?

If we don't teach them language other than simple commands so they can obey us, then they can lead a simple life of ignorance. Think how happy your cat or dog is when you come home. Imagine having a sexy slut on her hands and knees ready to suck your cock when you get home. She won't be fat because she doesn't get to eat unless her master feeds her. All she'll want to do is cuddle up next to you or sit on your lap, in between periods of fucking for hours at a time. In this scenario, the foid wouldn't even be alive if we didn't breed her, so she owes us a life debt and must obey us for eternity.
