my 1 year old male leopard gecko has a weird prolapse at his hinds and it has been there for about 2 days. I've tried giving him warm baths but it's not going back in or coming out. please advise on what I should do.
What you're seeing is a prolapsed hemi-penis. Get some human "Preparation H" or Karo syrup (at the grocery store - clear liquid that comes in a bottle) or make some very sugary sugar water --so sugary that it's like a thick syrup. Each of the above helps to shrink swollen tissues. Either soak the back end or find a way to apply it. If it doesn't help you're going to have to get him to a reptile vet and it's most likely that the vet will have to amputate it (that's not as bad as it sounds. It's a quick surgery which can be done with a local and the gecko does have another one . . . ).
