I would like to move Luna's litter box to the main floor of our home. I used to have it there but 2 of my dogs like to eat cat poo. The dogs are not allowed upstairs unsupervised so that's where the litter box resides now but I admit I tend to neglect it up there. Now that I am experimenting with cat food I want to monitor her stools. It is a covered box. I wondered if there was a brand of cat litter that would discourage my dogs from eating it.
