I'm not against racks. And if I got a Ball that wanted a tub, with the new shelving I wouldnt mind putting them in a tub. I just really like watching my snakes and their behaviors, I find it fascinating. And to learn their quirks is adorable to me. Loki, my first ball, will occasionally only eat if I put a black towel over his tank. I'm willing to accommodate whatever the animal needs. Humidity has never been a problem as I live in FL. I keep their waters full and mist their tanks during shed just in case.
