I switch brands...depending what is on sale. I really wonder if you guys need to be switching out the litter as often as you do. I really don't notice the smell...unless, as someone says, I break up a clump.

I do scoop every single day, in the am...and maybe 1 time a week at night too. I always add fresh litter to keep the boxes full- approx 3 inches of sand. I will notice an odor if the box gets too low...

I haven't EVER changed the litter as much as some of you guys do. I really haven't ever had the smell of cat in my house.
