lori-that site that lv4dogs gave you/us looks promising...and i may even try to convince mike we may need it for our home someday.

poor decker/poor you....how awful it must be.
i've tried cosequin but it didn't seem to do a thing! And the vets swear by it

they have also a zanex for cats that are nervous nellys that seem to work...a 25 milligram tablet cut in half every 12 or 24 hours depending how the cat does at first try every 24 hours.
ask your vet about it.

good luck lori
