Riley has been fine all day. He's been well behaved and active when I took him out to the pet store to pick up some extra things for his tank.

Ever since we got home, he's been acting a bit funny. He's laying with his head held up, but he has it turned, so it is upside down. He's also been very disinterested in much movement since we got back.

could the trip to the store and back have stressed him out too much?
or is he just being a snake?
