My older pig, Linney, is about 5.5 years old now... maybe a little older. Recently, I have noticed that, although her weight is not much different, it seems like she is carrying her weight more in her belly. When she stands, she looks/feels thinner. She feels the same as always when she is lying down (and her fat spreads out, for lack of a better descriptor.) Is this a normal part of aging? I realize she getting to be an old lady pig. Behaviourally she seems normal, eats, sleeps, begs for food, etc. Any insight on this from those who have had senior piggies?
