Lately, it seems Bill's been getting somewhat bony around his shoulders, spine and hips. He has very long hair, so it's difficult to tell exactly what he looks like under there, but when we adopted him back in March, he had a lion cut and was somewhat bony then too. It almost seems like he is losing muscle mass or something. However, when I feel his belly, it is fat and saggy (not just skin). When I pick him up, he still feels like a moose. He is estimated at 5 years of age and had a vet check/vaccines/deworming within a month after we got him (March 2013). Do you think it could be worms? I haven't noticed anything in his feces. He seems fine and is as lazy as ever ;-)
