The ignorance of some people is still astounding, I am currently doing some work in the Rockhampton Zoo ( a free council run zoo open to all public) and I am glad I do not have to deal with the public as just over hearing their idiot comments is enough to make my blood boil. The really scary thing is for every person who does get good advice and then puts that advice into practice there must be hundreds like the " they are cheap so I don't care" lady who never get told anything different and blissfully keep killing/ torturing thier charges until they finally have no pets.
In a way I would want people to have to have a reliable adult with kids/ teenagers when buying pets but at the same time that would have severly curtailed my wheeling and dealing as a teenager when I was breeding many types of birds. The standard comment from my Dad when we arrived at the shoping centre was " you are not going to the pet shop, and you are not buying any more pets" only to have me tell him "I'm off to the pet shop' and then find him later to show him what I had purchased. Thankfully all the birds fish and what not that I baught I paid for out of my own savings and I guess my Dad is a softy when it comes to animals, because he never even attempted to make me return them. If I had been forced to take my Dad with me to the pet shop in order to buy the various birds I wanted I would never have had the joy of having the many species I ended up with. Mum would have been an easier parent to take but the shopping trips where always a bit of a rush with only half day trading on Saturdays (no Sunday trade) and Mum was more interested in getting the groceries done than mucking around at pet shops. So I see both sides for the agruement and think it really needs to come down to sellers disgression (provided they really do care about thier product and not just the $$$$), and if they deem the potential buyer as suitable then sell to them, otherwise try to educate the buyer and if all else fails make an excuse for why that creature can't be sold to that person. The animal is in quarentine or being held for somebody else often works well without ruffling too many feathers.
