Maybe she wants salt? My rabbit will lick the wood in the doorways of our old house but could be diverted with a plate with salt on it. She hasn't done so since Logan sent little round salt licks that she apparently likes better than the one in her cage, which she has never bothered with.

I wonder if a trip to the vet is in order? Maybe she's got something wrong that makes her want salt - or iron? This is a wild stab in the dark, I have no medcical background whatsoever ...

Is she otherwise eating and drinking normally?
