Does your cat have degenerative joint disease?

With an estimated 10-15% of adults over the age of 60 having some degree of osteoarthritis, otherwise known as degenerative joint disease (DJD), many people will be familiar with, or will know someone who suffers from, this painful and debilitating condition. What is not well recognized is that DJD affects a high proportion of pet cats of all age groups, but particularly those 10 years of age and over.
