When I was a nurse of adults I loathed dealing with other people's poo. Now I deal with cat do and today two (!)mega-poonamies! Now I no longer have much if a sense of smell much easier to deal with!!
You have my sympathy. We have had to lock the cat flap since we have had Luna. Which means two litter trays. I'll be glad when they are both going out for their ablutions. :)
