I have a baby Sulcata that is about 2 months old. How often should I sprinkle calcium on it's food? Some say 3 times a week, some say daily. How often should I give it Herptivite? Also, I have been taking my tort outside for an hour or two daily. I know that when torts get sunlight on a regular basis, the calcium with Vitamin D3 isn't needed. Well, we're going to start having some chilly weather here in New Orleans, so I won't be able to bring my tort out like I have been. How often should I supplement with calcium with D3 during fall/winter months? Also, I've read that many tort owners in this forum use TNT (Total Nutrition for Tortoises). I may order this. Will using this particular supplement truly eliminate the need to use ANY other supplement? What are your opinions on this supplement?
