I did help him out a couple times and I find his rudeness to be equivalent to an immature child. I know children his age who are caring for much more advanced reptiles than a leopard gecko...and their maturity often surprises me. I had thought, now proven wrongly, that he was mature enough to handle the responsibility he took upon himself when he obtained this gecko...which, regardless of his feelings on the matter, should have the best possible life it can be provided in captivity. This includes keeping it healthy, well fed and making sure its dietary and physical needs are kept. Sand, whether fine ground or larger grain, is not good for ANY animals digestive track unless they're birds or another animal evolved to handle such things to aid in their digestion. Have you ever seen wet sand? How it clumps together? Imagine that in a digestive track where its getting roughened by stomach acids then constantly covered over by mucus because the body is trying to expel it. Now, usually it just blocks up the digestive tract.. however, it can also cause what is known as an iniceseption.. which is loops of bowl telescoping in on itself. Very painful and quite deadly. The only cure is surgery.. It also cause Interitis.. which is an infection in the abdominal cavity. All in all.. a nasty end to a fascinating creature that deserved much better. These things are why Leopard Geckos should not be kept on a sand or loose substrate.
Personally, I've only had my geckos for about 18 months...but I've hatched out 4 hatchlings already from fertile eggs and 3 more on the way.. My geckos are kept on Newspaper..or papertowels..provided calcium dishes and hides...I would never do something willfully to endanger my animal's health...and that is the responsibility you take on when you become the owner of an animal.. of any kind.
The people here are, for the most part, kind and very generous with their knowledge. They've helped me in the past with my questions and I in turn try to give back a little of that knowledge to the newer people coming to the Forum....your son's offhanded arrogance and rudeness is one of the main reasons alot of people don't speak up...They don't need a 12 yr old kid telling them knowledge they've accumulated in years of experience is wrong.. or not worth considering or even ignoring.
I do hope you see fit to teach your son some manners when dealing with people who help him...If not, I can't see him going very far in life... I'm sorry to say.. I mean no offense with that, its just the honest truth in my opinion.
