Hi, here's my first post in here! My children's python Artie is about 11 months old and has always had a fairly calm temperament. Just recently, though, he's been very snappy and active, wriggling around to the point it's hard to hold him in the one spot. I've been feeding him one pinkie mouse a week as per instruction by his breeder. I'm wondering why his behaviour has changed so much? Is it to do with the winter approaching or do I need to feed him more, or is he just changing as he grows older? Thank you so much!
