My friend got a small crocodile/ I think, it is a crazy idea, because crocodile is a very dangerous animal. So, it wont be comfortable for crocodile to live in the house. And, as for me, crocodiles should live in the natural habitat. Dogs, cats, parrots, humsters are the odrinary pets in my country. But some people are fond of exotic animals. I mean, lizards, monkeys, racoons, hedgehogs, tarantulas and so on. I think, that if you like animals and you are ready to take care of them, he can get the exotic animals
