I'm heading to puerto rico in a few weeks to see the wildlife there (I'm a major animal lover and photographer), I am told about some weasel-like animal (kills snakes) that the whole population is rabid (and that I shouldn't go anywhere NEAR them). Should I avoid the animals/cancel going there? i don't want to risk my health, i really want to get close to these weasel animals but im having doubts.

Is it possible for approacing a healthy-looking animal?
Is there a significant risk of these animals?
Any information on them?

Nice detailed awnsers please.
I really want to get close.
