Breeze Cat Litter Box

Does anyone use it for the purpose of testing for keytones?

It is a battle(I have not won once :sad: ) to test Bert's urine.

I wonder if I get this system and separate him from our other fur ball if this would work.
I am thinking of putting him in our bedroom(which is where he spends most of his day anyway) with all his supplies and hope for the best.
I know I do not put the pad in the bottom, but is it ok for the urine to pass through the litter that comes with the system?
