Morning, I want to try and get my little guy outside today for some natural light. I was thinking of just taking his cage outside. The question I have it the max temp today is going to be around 17 there is no wind and it is sunny should I still provide him with some heat like from a ceramic bulb or will he be ok without it? Also how long is ok for him to be outside? This will be my 1st time taking him out. Thank you for reading.
