Oh no, you don't get off that easy!!! The "advise" we give comes with strings. We demand pictures of your kitties as payment. We are never happy without seeing pics so we can oohh and awww over them.
There are many litters available that are not full of perfumes and do a very good job of masking/hiding odours. One of them is Swheat Scoop. It's available at good pet stores as well. A little pricey but you don't need to change the whole thing as often. Just make sure to scoop daily.
There are also pine based litters which are very nice. One word of caution though. If switching do a gradual switch of litters. 1/3 of the volume of litter, then 1/2, then 3/4, then all. It makes it easier for the kitties to figure out something is changing. You may want to get your peeing situation fixed before trying that.
