So i just got a Spider Ball python that i took from a friend because he was moving and couldnt take him with him. I have him in the exact same enclosure, i take him out and handle him just as often as the previous owner and i keep his enclosure the same temperature gradient. He moves from his cold hide to his hot hide, but i went to feed him yesterday about 9 days after his last feeding, a f/t adult mouse, which is what he was eating before (never had problems feeding him prior to bringing him home as i fed him for his last 2 feedings myself) but i tried feeding him and he wont take it, he reared up like he was going to strike and then he just ignored it, left it overnight (as he can be finicky and usually takes it if i leave it over night) but he still has not taken it.

Not sure if i should be worried? (Only reason im really worried is because my Carpet python is not eating either)
