These cats are going to be the death of me! Ugh. There has been three times ever, which have all been recently, where one of them has pooped outside the litter box (each time on the carpet). Each time it is when we are out of the house for a few hours (3-5 hours), never at night where they are left alone (they are not allowed in our bedroom anymore, as they keep Nathan awake (he has narcolepsy) for about 8-8.5 hours each night. I have no idea which of the four cats it is either. Does anyone have any ideas on what we should do? We already have multiple litter boxes, they are just all in one large room. Any help is welcomed. I just can't have this become a bigger issue, as I am pregnant again and can't clean the cat poop up while my husband is at work and I can't have my toddler play around the house and find a surprise pile of kitty poop!
