I've had my ball python for about a month now, and he is my first snake.

He is currently living in a 30 gallon sterilite container with holes soldered into the sides for ventilation. He has to UTH's-- one attached to the bottom, and another attached to the side in the same corner as the one on the bottom. His ambient temperature usually hangs around 79-81F, basking spot temps 88-91F, and cool side temps 77-79F. Humidity is usually 60-65%.

About two weeks ago, (1/19 to be exact) he shed his skin in his warm hide box, and since then has been favoring his cool one almost exclusively during the day when, I presume, he is sleeping. Since the shed, I have seen him burrow behind the warm hide to sit between it and the wall with the UTH, which was not something that he did prior to that. Before shedding, he did not seem to have a preference of hide box, and spent his time between them pretty evenly. Is his change of preference for hide box any cause for concern?

As a side note, the cool hide is a little smaller than the warm one, though I'm not sure he's having a security issue, since I've seen him sleeping with his head sticking out of the entrance.

Any insight will be much appreciated! Thanks!
