Tight hide

Hi guys

I just got my Reptile Basics hide boxes in the mail today. I ordered 2 small hides. My snake seemed to like it but when he's in the hide it looks a bit tight.
At first my snake had a little trouble getting in it but now he's totally inside of the hide. It looks pretty tight in there but he fits. Is it possible for a ball python to become uncomfortable from being a little too snug? Should I order the next size up? (I'm scared the next size up will be alot bigger.)

If he fits I'm sure he likes it. Its not a bad idea to have the next size up so your ready when its time for a larger one. I will put moss in hides that are to large to make it feel more secure.

I will often order the size I need plus the next size up to save on shipping.
