I got my first ball python about 6 months ago and she (not really sure if a male or female, previous owners assumed female but who knows) has been a very good pet. I think she is close to a year old. She's always gentle and seems to always be ready to get out and be held. She has always been a good eater. We take her out of her enclosure and put her in a plastic tub for feedings. (I know this can be a controversial subject, but hang with me here). Here lately she seems to be more aggressive when it's feeding time. A few weeks ago she lunged out of the tub for the mouse, before we even got the mouse to the tub, which was no big deal, but this was unusual. Today when I fed her, she took the mouse as usual and after she had eaten it, I reached into the tub and kinda rubbed her a little, which I always do before taking her out of the tub and putting her back into her enclosure. She pulled her head back into a striking position. I know that I should have heeded her warning and given her a little more time, but I didn't and she bit me. I was surprised by 2 things. One that she bit me, and two, at how it didn't hurt at all. I just gave her a few more minutes then picked her up and put her back into her enclosure as usual. Is this normal behavior or is there something that I might be doing wrong? She seems to be healthy. She weighs around 350 grams and I am feeding her an adult mouse every 8 days. We weigh her regularly and she is gaining weight, has good sheds, etc. Could it be that she's still hungry and I need to increase her feedings? Any help is appreciated.
