After talking to my vet i have learned so much from him. He was telling me about people he knows making playpens for outdoor time with grass floors!! He also said the sun is very beneficial for piggies, not the kind that comes through windows, the actual outdoor kind so i have decided to build my own outdoor time piggy pen for my back porch. Does anyone else have this or seen this before? Im excited to build a safe place for my piggies to play "outside".
