Salem gave birth yesterday and she seems to have given up cleaning herself. Today there was poo smeared on her back end and she seemed totally oblivious. I know while she was pregnant it was hard for her to keep her nether regions clean but I expected once the kittens came she would get back into the swing of things. I worry it will be unsanitary for the kittens to come in contact with it and she seems adamant not to let me clean it for her. I checked the litter and it's completely clean, I've been cleaning it twice a day lately so that can't be it. Any ideas? Should I be worried or is this normal behavior for a new momma?
