Snakes are raised as pets worldwide and you obviously don't know that there are two types of snakes, constrictors don't have venom and therefore dog bites are far more dangerous than theirs, and I'll be staying for a while so pray that you don't see me anytime soon because who knows I might have the snake with me then.
Also please mind your own business I don't know what your problem is but since you seem to know Qatar very well you should know that its a free country and people raise far more dangerous animals at their homes here just because you don't know about them doesn't mean it doesn't happen.
