I set my piggies out for floor time in our hallway and stupidly left out a 6 pak of soy drinks on the floor. I didn't think the pigs would be interested in them, but clearly I was wrong! About half an hour into floor time, my husband screamed...the pigs had eaten a quarter sized hole out of the tetrapak drink boxes and were enjoying the soy milk! I couldn't believe it! I didn't know pigs liked soy! Yikes! Hopefully they'll just poop the tetrapak out of their systems.
