To me, cleaning the cat litter trays. Everything stinks to high heaven. One practically needs a Hazmat suit on!
Unfortunately, my cat was born & reared as a 'house' cat by someone else. Not allowed outside. I'd previously always allowed my cats outside during the day, but locked-in at night. Their 'overnight' litter tray was hardly ever used.
Hate it when this ITablet goes 'off-line', which it frequently does, & of course, at THE most inconvenient time! So much time is wasted!
