I have two female kittens and the mother at my apartment along with 3 other unrelated cats but the kittens will not seem to get the concept of using the litter box. As I said the mother is even here we have 4 different litter boxes one especially for the kittens in a low traffic private area near where they will have their accidents.The sides are low the litter is cleaned daily I put them in the box several times daily and drag their front paws in it. I reward them when they do use it and when i catch them not using it I just place them in the box and show them the paw movement. I do everything I can possibly think of doing and they still go in the floor even right beside the litterbox sometimes and it's driving me crazy!! I just don't understand. Their mother is here with them too I would definitely think this would not be a problem. And with our other 3 cats i dont think its a territorial issue they never go to that box or in that box they don't bother the kittens at all. We just got that box when the kittens were born about 2 months ago on April 23rd so they're used to the other boxes in the apartment. I wouldn't think the number of boxes is an issue either this is a small one bedroom apartment with 4 boxes already I don't have room for anymore but maybe that could that be the problem? I just dont understand. It's driving me nuts. What else can I possibly do?
