My piggies only let me reach in their cages and stroke them and pick them up, no one else... but they prefer to sit on OH when they are out (especially to pee on him - they won't pee on me).
I don't really mind they fact the like sitting on him more because he's also their out-of-cage loo and if I say "back?" and hold my hands out, they put their paws in my hands if they want to go back to their cages. Coconut is the best at this and it makes OH jealous as they just look at him and go ?/ when he tries it haha!
