I've just opened up a new bag of hay for the bunnies and it has a very odd smell - almost like diesel! It's all I have at the moment so I put some out and they are happily munching away on it, but I'm not sure I'm happy for them to be eating it really. Anyone got any ideas what might have caused this? It's from the not so wonderful P@H as they were the only place still open on my last minute after work shop!
