So, it appears that Tom the cat is a high pee-er (how do you spell that??). Current litter box is one of the Nature’s Miracle ones with specs that include 11" high. It is about half an inch too low based on recent observation.
In the past I have been advised against top-entry litter boxes. To be fair, it does seem a bit like entering a porta-potty from a hole cut in the top. Likewise, have been advised against covered ones on general principle, though there is apparently a problem with the urine seeping through the seam between the tray part and the lid part.
I found this Modkat one that seems pricey, though the reviews are generally good. It is covered, but the lid flips back. Anyone used one? Do you really need the liners?
Or do I just go to Target and try to find a smooth-sided storage container and modify it?
Any other ideas? And do I panic that this is a sign of some sort of medical issue? I hadn’t observed it before, but the area under the box has been damp on occasion. It’s in a bathtub under the tap so I assumed some water had leaked out somehow. Based on today’s cleanup, his urine isn’t massively stinky, as cat urine goes.
