My husband and I are moving to a duplex with wood floors. Currently, we have a litter box that we created from a big plastic sterilite storage container. It is cheap, but creates a mess when the clay litter escapes from the box. It is so messy I have to vacuum a few times a week to clean up the clay. I am concerned that with the wood floor, the clay will get stuck between the cracks in the wood, and our new place will be a lot bigger. I don't want to be vacuuming like I am now and feel that the more I do vacuum the floors the more likely it will be I will ruin them. This is a concern because we are renting and the wood floors were recently redone. Does anyone have a suggestion on a litter box that keeps the litter in confined in the box? I would use another type of litter, but have not found anything that works for my cats. I refuse to use any type of clumping litter because they are environmentally hazardous and other alternative enviromentally safe litters like corn, well my cat simon will eat. Do you have suggestions for me? Thank you.
