Hi there,

I've never heard of "nosorb," but I'm assuming it's a plastic litter?
Our vet gave us a tiny bit of plastic crystals that didn't begin to
cover the bottom of the box.

What I did was feed Abernathy wet catfood with LOTS of water mixed into
it early in the morning. I then parked myself, with a syringe ready, in
the room where he was secluded.

Within an hour he was in and out of the litter box without going, a
little weirded out by the litter. I decided to add a cup of his regular
litter into the middle of the box, trying to keep the corners free of it.

That did the trick, he smelled his own litter and went, and I rushed
over with the syringe before it soaked up into the real litter.

Good luck tomorrow!

Rhonda
