I hate these nasty things!!!!!!!!
We've been using Dr. Elsey's litter for about a month I'd say. I accidentally bought scented Scoop Away previously. I was hoping it would help with the urine clump situation, but it hasn't.
The kittens have two boxes and the litter is 3-4 inches deep at least. I actually cleaned out their pans altogether yesterday and added new litter and was sure to put in about an inch more than I had before, hoping that there wouldn't be any urine balls stuck to the to bottom. No luck.
My problem with them is that when I'm unsticking them from the bottom, they break apart just a little bit and leave bits & pieces that are too small to get caught up in the litter scoop, which end up getting mixed in with the rest of the litter while I'm cleaning it. I feel like this makes the litter nastier and less attractive to kitty noses.
I clean their boxes a minimum of twice a day so it's not that they don't have room to pee. I've seen Simon dig down to the almost the very bottom to pee right after I cleaned it out! Grrr....
Do you have this problem? How do you deal with it? Is it just a fact of kitty life?
