I'm a cat person. Very probably due to toxoplasmosis. Any-who, the first post made me laugh, because washing even a docile domestic feline is a chore, so letting the toilet do it would be brilliant - if it worked. Also cleaning a toilet is a chore, so letting a cat do it ... would be brilliant. It's obviously nonsense, but it makes cat lovers laugh. And the dog punchline is good too.
The above does not make sense, you should really check before you post so people can follow what you are trying to say.
