I have had my Leopard gecko on calcium sand for about a year now, and I have been doing some research and realized that that is very bad! It was too late, and I think he was impacted. I soaked him for about a week and he had a great big poop, but that was six days ago. Since then he hasn't pooped. I can't take him to the vet, it's too expensive( Im just a kid). I dont know what to do so many people have given me totally different advice. The worst thing is that I can only guess what is wrong. Sorry I dont have any more info. I would really appreciate it if somebody could help me.
