Normally docile snake being bitey

I used to feed him in a different enclosure, but started feeding him in his tank after hearing that he'd think every time I pick him up, I'm moving him to eat, and I believe that this is the issue. He used to not bite or be angry at all, but since I started feeding him inside ihs tank, he's been irritable. His eyecaps aren't left over from the last shed, he was fine after shedding and only got pissy after eating.

I have a couple of snakes that I feed in different enclosures, and they're not bitey. Last time one of my gentle boys got bitey, he hadn't poo'd in a while. I'd be grumpy too if I needed to poo and someone was messing with me. :rofl:

Feeding inside the tank does not make a snake aggressive. I wish this would stop being spread around. In fact with many BPs the act of moving them to another enclosure can make them not eat.

Also not handling the next day is to prevent a regure not to prevent biting.

Let's get back to basics. What type of tank is he in? What are the temperatures? If temps get too high or low they can make a snake grumpy. What's his humidity?

Being fed 3 times in a week is pretty often even if they are just small mice. I would back off from him and give him a few days to digest all the food he has had recently.

Then try again. He's been getting a lot of food recently and may be still in feeding mode.

First thing I would check and double check are temperatures.

Is his husbandry good? Humidity levels, temps, etc? Even though he just ate, he might still be hungry. Especially since he's been off feeding. Try offering him a snack, nothing huge, but just a little extra something.
