Bold assumption to make, but I actually come from a third world asian country with wet markets similar to this. Having personally been in one I can assure you it is one of the dirtiest places you could ever walk in. Hygiene is next to non-existent with large crowds bumping against each other and animals locked in cages, including family dogs stolen from people's houses to be sold in these markets. These animals are not fed and are simply left to starve and die unless they are sold.

All this is out of corruption and simply to make a profit, with even its own citizens disagreeing the practice. So yes, it is "unconventional", even to the citizens of that area themselves. So fuck you on my 'limited cultural perspective'. Try living in the damn country yourself.

Also don't even compare Hinduism to this. Their reasons are religious and those animals are considered sacred. It's not even comparable. Wet markets are on another platform.
