I'm probably very wasteful though when it comes to the hay. Every time I walk by the cage, which is often, I give them a handful and in the mornings, I give them a couple of big handfuls since I'm out all day. I guess I freak myself out knowing how important it is for them to eat all day. I leave it on the floor of the cage because they were sticking their heads inside the holes in their hay bag and I was afraid they would poke their eyes out. Now they bury themselves in it, but the hay has more room to move around with their body movement. Call me paranoid!!! When I do give them the hay, they now expect me to dig out the seed heads and give them a treat. Silly piggies. I just have to say this - last night I couldn't stop laughing watching them play tag!!! I'm pretty sure one of them (or both) were in heat. One would sneak up behind the other and give a slight nudge in their bum and they would take off chasing each other around their hiddies and in and out through their tunnel and back again. Talk about entertainment for me, it was hysterical!!! A great way to get ready for bed!!!!
