Alright so a friend of mine is basically dumping some leopard geckos on me. I don't think learning to care for them will be an issue. But, I am certain that the geckos have been kept at fairly low temperatures (around 40-50 degrees Fahrenheit) for an extended period of time. I assume they will probably have health issues and I just wanted to ask the community if they knew of any common signs of illness to look out for. Any tips are helpful. I have never had lizards before, only snakes.
