Kinda hard to tell from the photos, but he doesn’t look all that thin to me. Carpets are very long, slender pythons. I’d give him a bit to settle in and then offer a small rat just to gauge his appetite. He could surely take a medium if you feel inclined to go to the pet store for a bigger feeder, but at 10yrs old he’s done most of the growing he’s going to do and shouldn’t need an overly high calorie diet to maintain his physique. Welcome home, Squeeze/Hugs!
