So my wife and I purchased a ball python from petsmart along with its 30 gallon tank that came with the lamps, carpet and thermostat and humidity gauge. We have a large log hide, rock, branch for climbing and water bowl. We put shavings in there and let him settle for a few days (3) and tried to feed it. First time nothing, the last time it did strike and ball up.. let let it go. We have tried pinkies and fuzzies. Are we doing something wrong?
