From your picture , that is a classic planter gait. If the vet cannot see neuropathy from this , what the heck does he think it is then?
One of the vets where I take my old Tyler was adamant that what I saw develop over a few months was not neuropathy. It was !
If you look at my signature, you will see that Tyler is a very elderly cat. Before Christmas he had got to the point of mostly scooting as he could not sort out his back legs really. He had quite extreme neuropathy & I did wonder if it would ever come right but it has.
I started him on the B12 methycobalamin tablets + folic acid. I cannot get zobaline here but it is the same thing. After several months Tylers planter gait has completely gone. He can be unsteady because of the one back leg/knee joint but that is muscle wastage and arthritis. Not neuropathy.
When you say having problems with the litter tray, do you mean holding himself so he doesn't plonk down in his poop?
...edit....
Also, once the diabetes is more regulated and the numbers lower from wherever they start out at, that also helps.
