I was thinking of making a hidey from a birdhouse gourd. Does anyone know if gourds are harmful to Guinea Pigs if they chew on them? I noticed pumpkins and squash are listed on the safe veggies list, and gourds are in the same family as them. I thought the birdhouse gourds would make a nice natural source for a hidey house, and they are basically free since I grew them in my garden. But, my second thought was are they okay for my little guys to chew on. Does anyone know for sure or have an opinion on this?
