I do not identify with being feline or canid at all, so can't say the tailbone thing has ever happened to me. But, I have mentioned in here, once or twice, that I process the fight or flight mechanism quite often. Or, when i feel I'm in a dangerous situation and flight is not an option, I do know instinctively how to hide myself very well. When I chose my animal fursona, I didn't just start to have these instincts either. These came with years of training and practical use from being a Recon Scout in the army for 11 years. It wasn't until about 8 years out of the service did i realize just how similar I was to a certain species that became my fursona.
