I was struck at once by Elysia, but that was only a few days after I had gotten her, and she wasn't used to me yet and probably grumpy from her trip, but she loves me now and hasn't tried since ^_^ Though she has struck at a mouse at feeding time, made it drop out of the tongs, then try and go through her glass tank to get me. I was the hottest thing she could sense I guess, cause the mouse fell into her water dish and probably cooled it off a little ^_^ I dragged my finger across the glass tot he water bowl and she found it right away though.
