With the litter tray cleaning? Sage, Astryd and Darwin haven't. (I scoop the trays twice daily.)
But Carrie Bagpuss, she had a "where are you?" yowl, a "I'm going to be sick, please come and reassure me" noise and a "the litter tray is now very smelly, please sort it out" yodel. She may have had dementia but with some things she was still on top form.
(When she was going to be sick you were expected to sit rubbing her back and holding her secure, as you would with a human. Funny old thing, I miss her loads.)
Jack rarely used a litter tray. And Toby and Parsley never let me know they'd done anything either. Seems just Madam Mog expected prompt service.
