Might be a long shot, but is there bad weather near or not so near to you? Maybe he's sensing some type of environmental change???

I know what you mean about Vet bills for our lovely seniors, they seem to add up really quickly as there is always something. One thing I did with Kody was to get health insurance for him. So at least if something goes on with him I won't be hit with a big Vet bill.

Please update us as time allows.
