How about people who have been working with ball pythons for 20+ years? Those considered the authorities on ball pythons? Those that the top veterinarians in the country have on speed dial? Would you respect their opinion?
Because people like Kevin McCurley of NERD who wrote The Complete Ball Python and Dave and Tracy Barker (who are top renowned herpetologists, btw) and wrote Pythons of the World, Vol II: Ball Pythons all recommend that you do NOT house ball pythons together and see no benefit in doing so.
