I just recently acquired two young cats. We use johnny cat litter, and frankly the smell of the litter box is nauseating, the smell is so strong. Both of the cats use the same litterbox, i was wondering what is the best litter for odor control? I also scoop out the solids once a day. Another thing is, my cats seem to deficate quite a bit, and i am truly amazed how much litter they produce, could this be that i am over feeding them? We feed them 4 Tbsp each of canned food and about a palm each of hard litter once a day and sometimes they receive table scraps. I really appreciate your time and help, please let me know if you need anymore information, thanks again.
