Hi! I am located in Arizona, we found this little guy in our garage hiding underneath our tortises indoor enclosure! He looks like he got beat up by another animal not sure what. He has his skin on his head ripped, as well as his back, and his tail seems to be holding on but also pretty beat up. We want to give him a shot and try and help him and rehab him back. I’m in tears over this little dude, we know nothing about geckos? If that’s what he is. We don’t know where to start, so any advice, help, what to feed, how we should do this or if euthanasia would be the more humane thing to do. Please help!!
