I am new and I am sure this has already been talked about however looking at the recent threads I didnt really see anything. What is the best litter to cover that awful poo smell!!?? I have been buying boxes of baking soda at the Dollar Store for about 50 cents a box and putting a whole box down in each litter box. Then cover it with Arm & Hammers new double duty cover the smell urine and feces and THEN put Arm & Hammers essentials (that stuff smells pretty good for litter) on top of that! It works for about a day and then as soon as a kitty goes #2 I have to scoop it right away or the whole house stinks! I change the boxes once a week and this is getting expensive! What is everyone else using??
