Anyone use a uv lamp with their bun? Ruby's doctor thinks she needs one. Vitamin D. He went over all these studies he's read (he does that every time he sees her). So I got the bulb, gonna get a timer, as he suggested.... But not sure when to have it on. Evenings for about 4 hours? We really get very little direct sunlight in. Covered porch and trees. It's kinda dark without lights on. I've been reading a few articles and am thinking it might be a real good thing for her. Anyone else have experience, thoughts, opinions?
