Hi Shyla,
I'm glad that you took Dick to the vet in order to identify what might be causing the inappropriate peeing. For information, sometimes when diabetic kitties are not regulated properly they may develop toileting problems, but they tend to resolve when blood sugar levels get better controlled (worth a mention to your other half!). If you're getting blood work done in the future, I'd suggest asking your vet to check Dick's B12 levels. Sometimes diabetic cats develop neuropathy (nerve damage) and that might feed into the litter box issues. Supplementing the diet with B12 methylcobalamin can be a very effective treatment for neuropathy. Zobaline is a methylcobalamin supplement suitable for diabetic kitties (no sugar in the tablets).
Be sure to let us know how Dick got on at the vet, and whether there is anything else we can do to help.
