My lizard has no tail. That is alright. Most geckos loses its tail when something grabs on to it or when the tail gets stuck on something. When my gecko lost his tail, it was a complete accident. We were downstairs and i brought Avocado with me, because i wanted to show him the living room. My mum and dee had just finished it, even though there was no furniture. I had placed him on the carpet and he jump, he had his tail at this point, and i tried to grab him but i grabbed the closest thing in my reach, which was his tail. It came clean off. I didnt know which one to grab. i grabbed Avocado because he was still trying to escape. His tail was wiggling in the palm off my hand. I ran up to my mom crying with Avocado in one hand and the tail in the other, desperately attempting to put them back together. I told my mom that his tail curled around the heel of my shoe and he jumped the instantly coming off. She knew better.
In moral of this story, tell the truth and when your geckos tail comes off, don't freak out.
