I was at work and my door was closed. My sister opened the door and the cat got in and was pawing at it. The cat broke open the roof and attacked gecko's tail and took his leg clean off! What kind of first aid should I do?
If it is a big wound like that seems to be i would use neosporin and some clean gauze or cloth to try to get the bleeding to stop. (neosporin is safe to use on beardies and snakes so i assume it is for them too). You will probably want to try to dry the wound after you clean it and take it to the vet as fast as possible.
If this happens in the future then if the tail was dropped and not bitten which they generally are then it will be fine but for the leg clean it and call the vet to ask about the next step hope this helps!
