I was wondering if anyone here knew the expected lifespan of the Mexican Black King? I've seen everything from 12 years to 25, and am rather confused.
My male is 9 years old, and has started some cranky behavior in the past six months. He looks fine, and eats normally - and no changes to his home or care. Before I put it down to just needing more handling time I'd like to be sure he's not just getting older, and maybe needing to see a vet. I'd hate to be unknowingly causing him pain or anything. Anyone have any suppestions? Thanks!
