I work at a pet shop and wouldnt even think of selling a 12 year old any kind of monitor... Your talking about a large lizard here....And whenever we get a sav in thats calm enough to be held...we take it to a vet..its probably sick, haha
The anole was mentioned because its often looked at as a disposable pet....its not, and i dont recommend at all getting one...
If she wants a reptile you are gonna be the one taking care of it...buying dozens of crickets every week, giving it the proper vegetation, and making sure its all dusted with miner-all or some other vitamin/calcium supplement. Not to mention they do grow pretty fast and when discussing enclosures for these species your talking feet not gallons.. SMALL ENCLOSURES DO NOT MAKE FOR A SMALLER LIZARD...(well...unless its thin and dying)
Of the two I would say a bearded dragon but before you buy you need to read....alot.....Know absolutely everything about the living being that your getting and if you go to the pet shop and he doesnt know what hes talking about, then do not buy from them. Sketchy shops have sketchy employees that are only interested in a sale and will tell you millions of lies to get one. There are countless breeders online that sell great animals which you will be much happier with in the long run. Whatever route you take, you should find a reptiles/exotic vet nearby that you can have him checked out at as soon as possible after purchase.
Annnnndddddddd,
Alot of the kids I see that want a pet reptile are more interested in the novelty of it, with a few exceptions. Make sure your daughter is mature enough to realize that it does need to thermoregulate and this isnt something she can walk around all day with on her shoulder.
..end rant..
Im sure someone else will add to this...let us know if you have other questions...
