I've had my ball python for about 4 months, and had trouble getting him to eat. He wouldn't take mice that I thought would be right for his size, so I've had to get smaller ones for him. He also went on a feeding strike for a bit, which he is now off of, but still seems to be having a hard time taking larger mice.
I recently noticed that his spine/back looks a bit more triangular than rounded off, which I heard means that the snake is underweight. He hasn't yet shed in the time that I've had him, and hasn't grown much. He's currently only at around 200 grams at 7 months old, which from what I've seen is very small.
My current plan is to try to give him more food more often (maybe once every 5 days at large adult mice?) in a sort of "feeding burst" to get him to gain weight. Would you guys recommend I do this?
I'm also am currently trying to get him onto large adult mice, but like I said, it's a bit tough. If I can't get him to make a switch, should I try to give him more than one smaller mouse at a time?
*husbandry is pretty normal. I've got his heat mat at around 90 F and humidity at 60-65%, two hides, etc. etc.
