DCat needs to provide a urine sample for the vet.
I just got the Katkor non-clumping litter which they recommended. It turns out, it's stoo small so the whole thing has fallen through the holes of the top tray into the bottom tray (where wee collects).
I can't put the Katkor in the bottom tray as it would be too sunken into the box, and it moves if I don't put the top tray on top. Plus DCat no longer uses her tray so chances are she won't use it if it feels very different. She's locked in for the day to force her to go there (no idea if this will work).
Does anybody know if you can use her usual (old) wood pellets instead, or would that contaminate the sample? They are quite hard and only soften if soaking.
The other thing I could try is to put some kichen paper over the holes so the wee soaks through the paper, but will this work? And would that constitue contamination?
