Re: squeek when i open my door
This means your piggy is happy! He/she thinks you are bringing food to them.
Most guinea pigs can be trained to squeak when you bring food to them. When I feed my piggies, I crumble the food bag with my hand, and they all start squeaking away! Just the smallest movement of a bag makes them think food is coming!
But don't ever trick them just to hear them squeak. If you do, and don't bring them any food, they will lose the habit.
