Metabolic Bone Disease is a very common disease in reptiles but a lot of people dont know why it happens. I have seen many cases of Metabolic Bone Disease in my experience with reptiles. One of the first thing you need to know is what kind of lighting you need to have, for the specific reptile you have. Different reptiles need to have different amounts of UVB. UVB provides a lot of minerals that the sun naturally gives to them in the wild. If the do not get enough their bones start to crumble and brake apart.
Lighting needs to be one of the first things you think about when dealing with a reptile. The bulb that you choose need to have UVB in it because the UVB provides vitamin D3 in it which provide the calcium that the need to stay healthy. Another way to give them UVB is to take them outside with you. The sun is the best source of calcium and also a good heat source for your reptile to.
Another way to prevent metabolic bone disease is to provide a vitamin supplement for them. make sure that it has calcium and phosphorus in it the best ratio is 2:1 it will provide the best results for the health of the reptile you own. There are to diffrent way to give it to them. One is a powder form and the other is a liquid spray for. My self I use the powder form. The way I get them to eat it is, I put their crickets in a bag and put two spoonfuls into the bag, then shake it. That will lightly coat your reptiles food for you. If you are using a mouse only dip their hindquarters in it for best results. If you want to use the liquid form. You need to spray their food with it and I also put a little in their water to. The best way is what work out best for you. But make sure that you are getting them some whichever way you choose to do it.
The last thing you need to know is to always think about the healthy of your animal if you think something isnt right make sure you get it checked out. Never let your reptile get sick because it is easier to prevent than to fix.
