Thank you both! Yes, will have a phone call with test results tomorrow. Vet is leaning towards kidney issues. Prostate is fine; and no temp so less likely to be a UTI. (Also, males are less likely to get that than females, which I didn't realize.)

I took in a urine sample (he is offering so often, that was easy! ) and they took a blood sample. Poor Ozzy, he doesn't trust people at all and this was such a traumatic visit for him.

I have been using a vinyl backed mattress protector. I put it on top of my bed spread, then his blankie on top, so in theory I only have to wash the blankie and maybe the protector. So last evening I was tired, set it up wrong side up (vinyl was on top) so his water just rolled off onto my bed.

Will post an update tomorrow.
