the one thing you have to watch with straw and especially hay, is that it molds very quicklyJust wondering if I need to switch to straw next time in case .... Does it hurt them if they eat a little of it? One funny thing I noticed is occasionally there will be a red shaving mixed in and they notice them right away and play with that one red shaving! I've even watched them fight over the red shaving lol. It must taste different.
