There is a big patch coming for Cats and Dogs, but the modder is very informative on how to install it. I am not sure if I can link it since there is another mod on the same page which violates the forum rules, but it is the MCCC mod by Deaderpool.

There is a mod? Can you please link me to it? I desperately need something to stop it! I have a vampire with superspeed and he keeps running off to the darn sink upstairs, too fast for me to stop it. This so much! It was so bad for me that I had to use a mod to stop it! Running over to the sink with this 'wash dishes' action queued up only for it to disappear once they're at the sink because there are no darn dishes. A difference of 80 may seem like too much. It changes the default maximum of in-game storage hampers from 20 piles of clothing to 100. Egureh’s Larger Hamper Capacity mod is pretty self-explanatory.

My well-mannered Sims keep washing non-existent dishes. Another Sims 4 Laundry mod that I highly, highly recommend (because once I installed it, I never looked back). Well, at least yours do this only after dinner when they actually have something to wash.
