National Geographic did an interesting article on this in their January 2010 issue called "Asia's Wildlife Trade" that's worth a read. In it you'll find mention of Jatujak Market and some cute little fur balls known as slow lori they claim sell in Japan and Russia for the equivalent of $1,000USD. Exotic pets just never made sense to me; bringing a crocodile home never seemed like a wise idea.
Five good reasons not to keep pet crocodiles at home
I've found myself off the beaten track in Jatujak and seen the rings where cock fights are held amid the exuberant shouts of those there betting on them while they slash away at each other, but let's address the grey areas another day, shall we?
There's an enormous section of fish, aquariums and supplies at Jatujak - the largest of all the pet areas by far, by my "guesstimate". Rows of relatively permanent stalls lined with tanks, some specializing in a specific type of fish, such as fantail goldfish or what we in the US would call "Siamese" fighting fish - although it didn't occur to me to ask what the Siamese call them!
One shop had nothing but baby geese, chickens, ducks and the likes...
There are also many, many places to buy reptiles of all stripes (and scales) - and puppies by the dozen. It's a fascinating menagerie - somewhat like taking a stroll through Noah's ark - and we'll take another look at it soon.
