I second all ideas above, especially replacing plastic socket clamp lights and using overrated extension cords/dome lights. I would check into products like zoomeds lightstand or placing plant hangers on wall, to suspend lights from; instead of the clamp variety. In South Carolina, new home...
Like bunny said, warm shower should do the trick. Once I had a baby panther do a swan dive into my full coffee cup, little warm shower and he was as good as new.
I have both scheffleras, umbrella and dwarf. My large veiled eats all new growth on umbrella with no side effects. Sources online say toxic and others say safe.
If he would eat less of it terrarium would look better :)
Ficus and arbicola are good. Schefflera actinophylla or umbrela tree is another good one available at big box stores sometimes. It's less compact with bigger leaves then arbicola. My veiled devours the new growth on his.
I know it would freak me out if I had a man eater lion staring through my kitchen window every morning. lol but chams are curious critters that aren't afraid of much.
If you had a planted terrarium with separate drainage layer and plants, you could reduce watering. But impaction, mold and flooding can be a issue, without careful husbandry. I would look into false bottom or hydroton drainage layers...
Lol been doing this for my baby nosey be. My 13 year old says I can't do it in the front yard and the neighbors look and shake their heads, saying you can have all the bugs in my lawn too. Lol good fun and babies love em. :)
