I fed our year-old greenish rat snake three pinkie mice last Saturday (Feb 10). The snake has pooped a few times since then, but nothing significant. He also has a soft lump in his abdomen area. Should we soak him in warm water? Has anyone else experienced this? As a little background, we've had the snake for a little over a month and he's fed regularly on three or so F/T pinkie mice a week. He won't eat anything with fur on it, even though he's large enough to eat mice bigger than pinkies.
