Spikey was pretending to be a guard dog! lol I'm glad he's fine, it's always better to have a strong protective worry reaction than be all blase about it. I won't bother repeating the reassurances, other than to say you have quite the little man there - lol being all ferocious!

(Though, I think I would whisper that he scared you, so he can remember not to do it again quite so vigorously!)
