there's a lottery game in Brazil where you choose animals called "jogo do bicho" which is simmilar to lottery, each 4 numbers are animal, not fully sure
these are forbidden by law too (only the official government lottery is allowed) but not hard to find in the streets.
each country has its rules and of course some things should be forbidden,but many times they make regulations out of stupidity, that hurt more than help.
Lots of places in the world have some odd laws which might seem not usual or not normal in the eyes in most people but it cant be helped because decisions and laws made were final.
We can give out criticisms but nothing could be changed.
Because sometimes it is already their way of life, like from their tradition or culture. We can't judge them based from how we brought up as around the world, we have so many differences at how we look at things. It may be cruel in our eyes, but for them, just a natural one. So every place has their own judgment what is right or wrong when it comes to this aspect.
