The salt lick?? I wouldn't.
I have never given salt to my rabbits. I know it probably won't hurt him but all the salt they need comes in their food and treats.
On a side note, cleaning Acacia's condo today.. Been at it for 45 mins so far. My vacuum needs to charge and I have baking soda down on her carpet, her blankets are in the dryer and she's impatiently waiting in the bathroom/basement. She likes it in there but she's mad bc I clipped her nails and she wants to go sook in her house :p
Oh the joys.
