When I had posted this thread, after a few days of nobody replying I just stopped looking. Well, there was a question about the number of times people posted in what secton (dog, cat, pet, other). When I searched to see how many, I noticed people had replied and I missed it.
Yes, I was talking about the stuff that you spray on their food to make their urine and waste odorless. I use Simple Solutions on the mattresses. I believe it has the enzyme action in it. I was just wondering if the spray stuff made their urine odorless. After thinking about it though, I don't know if that's such a good idea. As was pointed out here, one of the signs of a urinary tract infection is urinating outside the box. When my cats have urinated somewhere else, the smell is the first thing I have noticed. So I decided against the spray just for that reason.
Carrie, I had to laugh at this "Try taking whatever they play with, lie on, sleep on along with bedding that the family have slept in and rub it on to the new stuff as though you have nothing better to do! (Do not let your friends, even good ones, or neighbours see you doing this!) " I think they would have me committed!!!
Thanks everyone for the advice. As Carrie said, after the new smells mature, the cats will accept the new smells. That was what happened here.
