If it's a jacksons, yes, I do spray directly untill I see their mouths open and close, which means I know they are drinking!
I spay from the top, so it's like rain down on them and they love it.
Veiled I do not spray directly because they hate it. The water just beads on their skin and rolls off, very different from jacksons.
What do you think they do in Kenya when it monsoons, ware little rain coats and little umbrella's!!??
