Just wondering if anyone else's cats do this. Whenever my Bengal, Gabby gets startled or is playing a serious game of hide and seek with her feline sister, she puffs her tail out. I have seen cats puff their hair up on their bodies if they feel threatened, but Gabby just does her tail. And it gets absolutely huge! About as wide as her body! It looks quite hilarious and like a racoon's tail. Hence the labelling of the behaviour as "coon-tailing".
