I wanna know if they all applied those sentiments to all pets.

There isn’t a single domesticated animal that isn’t “gross” and has to be cleaned up after constantly. Dogs will shit on the floor when you don’t let them outside to shit in nature, but a cat doing what it’s supposed to do will shit in a box you have to empty regularly and shreds your furniture for fun. At least dogs only lick their balls, cats have the flexibility to straight up lick their assholes.
