Apply some basic engineering logic to your problem.
You need to first identify the exact problem. "Smells too much is too general".
You may have one problem or you may have multipal problems IE 6 different problems.
1) Where: Is the smell all over the house, or just near the litter box in one room?
2) When: Does it smell, after they go or all the time?
3) What: Is it a pee or poo smell or both?
4) Who: Is it both cats or only one of them?
5) Why: Is the litter clump or non clump? Do they bury it? If you changed it every day would it still smell.
I changed mine evryday once for almost a week and I still had a urine smell. I did a black light search and found one of my guys had a urinary tract infection and was going when he had to anywhere. I had to pull everything out and clean the carpet and obviously get him to the vet.
Good luck.
