I used to swork for a woman who had 24!
My job was to care for her elderly husband at night, but I spent more time dealing with the cats feeding schedule and cleaning out litter trays. In fact, when he died, she asked me to continue working for her to look after the cats.
The house was huge, and it stank, because the cats never went out. It was very cluttered and dark and full of old persian rugs, cushions and mad furniture, so it was like being in a trompe l'oile picutre - you'd be looking at an armchair, and what you'd thought was a dusty old cusion would suddenly move and yet another cat would emerge.
Lovely moggies, completely bonkers owner, bless her.
