Well my bf had his family's ones in pine, my friend's had hers in pine, without a problem. Then again they also never gave them hay. Or many veggies. >.> And me being me my animals get the best care :3 a room to play in, I'll be making some stuff out of fabric for them (tunnels and maybe a fabric/cardboard playpen?), veggies each day... except Honey won't eat veggies.
Here's a question... anyone's ratties act like fridge alarms?? xD
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
