A pig that isn't a pig

Guinea pigs are weird little things - called pigs but they aren't a pig. Classified as rodents but even that is debatable.
This one was visiting with my granddaughter & my huge fluffball of a ginger cat was scared of it.
How he ever descended from the mighty lion beats me, although come to think of it he does bear a lot of resemblance to the lion in the Wizard of Oz.
