Cat licking a clay pot

Question
We have a cat, seemingly healthy, who likes to lick a red (Santa Clara Indian) clay pot.  Is this dangerous to her?  Is it the sign of a mineral or vitamin deficiency?  Thank you for your answer.

Answer
I would remove the pot so she can not lick it or coat it with Bitter Apple.  

I have heard reports of some ceramic/stone-ware products containing lead, which is dangerous to her if she licks it--so just be aware and cautious.

Some cats will lick weird things because they are obsessive compulsive or curious, while there is always a chance of anemia or deficiency that is leading to the problem.  

If the behavior continues, then I would have a stool sample checked and some blood work to be on the safe side to make sure there aren't any underlying problems.
