A visiting friend once called me over, saying:
'Hester, I think your cat is broken!'
I sprinted to the kitchen, worried something was very, very wrong. When I came into the room, I started laughing and told my friend that Joris is just an idiot and doesn't know how to drink like a normal cat.
(I've tried different sized bowls, dishes, locations and heights. Sometimes he drinks 'normally', he just prefers to do it this way.)
