Help me with my litter box problem!?

Tidy cat multi-scope is the best brand name for this problem. If you have a closet placing it in there will help. Also placing an air freshener is an inexpensive way to handle odors. Be sure not to let it stay in there. Though it may be disgusting changing and cleaning the litter box more often will cut down on the odor. If you really have problems try buying a closed lid one and trapping odors inside of it to create a bearable shield. Whatever you do don't feed your cats certain kinds of food. dry salted foods are best. Wet canned foods like fancy feast will induce more urine and feces so watch to see how your cat reacts to certain types of food and good luck.
