well its a duplex house, but the only thing the people ever said before, was 1 cat and 1 dog,, so really, they only care about cats and dogs, never said anything about a reptile, so i dont think they'll have a problem with it, and its not like the old man is going to randomly come into my house for no reason, but as far as i know, reptiles are perfectly fine
You could ask their policy on "caged animals" like a small lizard. That might not freak them out as much as that horrible word "python" that everyone is so afraid of.
