Dolly's tricky hay

Trying to get Kiki and Hubert to eat enough hay is a bit of a challenge, so we bought this food that is mostly hay! I'm tying to trick them into thinking its a treat which should make them want to eat it! Kiki may not be daft enough to fall for it as after a few bites she went in huff! Early night tonight as Ive been really tired the last few days!
