There is nothing wrong with that add! Unfortunately some people do release unwanted reptiles into the bush. I know of several cases!
It's sad that it happens but some people find them too hard to look after and simply release them. It would be interesting to see how many responses he gets. He would probably get a whole range of exotics offered.
I have been given 4 saw shells and a spotted python, so it does happen. Personally i dont think the "i dont want to spend money on herps but i want some" type attitude would attract many offers though.
i picked up a free python yesterday from a guy who was going overseas...you may have seen the offer if you are on yahoo groups. It is a diamond/coastal cross that i usually don't show an interest in but i didn't want it to go to someone who wouldn't look after it.
last month i was lucky enough to be given a murray darling carpet python by a friend because the landlord didnt want it in the house he is about 6 months old
