Okay, little buddy! A pigsty is like a cozy little house for pigs. Just like you have your own room where you sleep and play, pigs have their own special place too!
In a pigsty, pigs can stay safe and dry. It's usually made of wood or mud, and sometimes it has some straw inside, which is like soft bed for them. Pigs love rolling in the mud and playing, so a pigsty is a perfect place for them to be happy!
Isn't that cool? Just like how we need a nice place to live, pigs do too!
