Hi, I just bought my first ball python today and he has only been here for a few hours and threw up his last mouse. The people I bought him from said today was feeding day so I assume he ate a week ago or so. I haven't fed him today as I will wait for a while for him to get used to his new home.

Could this just be stress from his new home? The temp on the hot side is 90 and 80 on the cool side, he's in a 20 gallon.

He is approx 5 months old.

Thank you
