As others have said, if you don't already own tarantulas it is a bad move to get an OW. If you do already have Ts what species do you keep? As far as them being "dangerous", it depends on your definition. If you limit it to "can it kill me?" then no. If you include "can it kill another pet of mine?" or "can it put me in the hospital with agonizing pain and other awful symptoms?" then yes. You should also respect your parent's wishes. Educate, absolutely. But also respect it if they still say no.Looking to get some old worlds but my parents are knda against it. They think they could kill me lol, can you guys give me some info i can pass on to them thanks
