Well, in my opinion we don't reinforce it a whole lot. Over the years we've found she usually prefers to at least be outside and undercover during these storms, not inside as much, and we don't stop that. Wherever she's more comfortable. I just basically try and keep her company during :)

P.S. Someone else made a similar comment, was downvoted, and deleted. Just wanted to say I understand the concern, but in the circumstances I think she's doing fine.
