I recently got a ball python- she's about 3 to 4 months old, give or take a month or so. She's about 20 inches long and an or so around at her thickest part. My question is when do I switch her from frozen pinkies to the next biggest food? I believe it's fuzzies? I've read so many different answers on this online, so I figured I'd ask people who I know have experience with ball pythons. Thanks in advanced!!
