Someone mentioned ziploc storage container but I just tried to make a hole with my soldering iron and it feels sharp and ridgy.... I don't want him to get hurt trying to go in. ... any better way to do this because it came in a set of 3.... I have 2 more lol... btw I am also glad I took him in because I am loving my new buddy LOKI.... and look forward to learning more and as much as I can on him. Right now I have no thermostat or dimmer so I'm going to keep my room at 80-85 until I do then I'll plug up everything. I have thermometer and heating pad but no thermostat and don't want to burn or overheat him.
