Mine eat too fast for the grass to keep up too! At my parents' cottage there is a mix of grass and clover that the pigs love, and my mom actually makes my dad go out and water the clover patches so they will grow better so the pigs will have more to eat! LOL!Oh, that's a lovely video! All those scrumptious piggies doing their bit for the lawn! I have had four of mine out four times recently and half my grass is gone already! Trouble is, it doesn't grow fast enough to keep up with demand!
