Hi, I have a 3 yr old python I adopted about a month ago. Today I just cleaned out and replaced the bedding of his tank for the first time. After I put him back he checked everything out like it was brand new for a good while. But than I noticed him bury himself under the mulch instead of going into his hide spots (which he seemed to love them both before). I went to handle him about 3 hours after letting him settle back in, so far he's seemed really comfortable with me, but he started hissing and wouldn't come out of where he burried himself. However, it's feeding day, so I just tried feeding him wondering if maybe he's just grumpy cause he's hungry. He took the food right away. Should I be concerned?
