I have a sphynx who doesn't cover his poop and I have a Maine coon. Between the two the litter box gets extremely smelly really fast. I live in an apartment and it's not that big and I'll be sitting on the couch and can smell when they poop from the next room. People come over and it's embarrassing. I can't run to the litter box at the exact moment they go to the bathroom every time they do. Is there a good litter box system you would suggest? Or some type of solution? Currently I use a large litter box with a dome top and use tidy cat litter with glade scent and regularly spray a deoterizer I purchased that has baking soda in it.
