Re: Petshops Suck...I Need All the Tips I Can Get If he is outside in the sun, you need a screen with good-sized holes (1/4") to let UV through and I suggest getting a MagaRay anyways for inside - the colder months are coming and you will need it then. However, when it is warm enough, natural sunlight is the best. To humidify, I suggest buying a humidifier and putting it in his cage once you get the big one built. In the meanwhile, spray him multiple times a day and keep his water under the light if you can - I find that makes the water evaporate and helps raise the humidity a little. As long as the water dish is secure and can't fall, it should not matter where you put it. I usually have Tito's on his shelf because that is where he was pooping and that was the only way I could manage to "potty train" him. The floor is more safe, but as long as it is secure like Is said it will be fine in either place. The calcium should not constipate him. Just be sure that you sprinkle it like salt and yes you do want to give him a little each day. Be sure also that you have pure calcium with NO D3 and NO Phosphorus. JUST calcium. He is little and thinks he is prey and you are a big, hungry predator. He will be shy for a long time. Just be patient and gentle and move slow. It may take months or even years before he calms down, but just be patient and you will get there. To warm him in the night, get a Ceramic Heat Emitter. It produces heat with no light so he cal sleep and still stay warm.
