I notice there are a lot of posts saying that the cartridge gets saturated too soon with urine.
My problem, however is with #2 - the waste storage compartment is simply too small. I find that in less than a week, my two cats completey fill up the waste part of the cartridge and I have to empty it.
Is anyone else running into this? How often do folks have to clean out the waste cartridge? Are there any plans to make replacement cartridges with larger waste compartment?
Thanks!
