I don't think it would be such an issue to have a snake at an elderly home. The only problem is that maybe some of the elderly do not like snakes as much (frightened) and they fear it may try to bite them. Now, if you tell them it's a python, they may immediately think "constrictor" and start to fear it even more because all they will think about is that snake becoming large (20+ ft.) and very thick, able to constrict one of them. Some people may not even be afraid, though, I know two people in my family who just flat out hate snakes of all sizes. They don't live at an elderly home, and they do visit often. My grandpa is the most fearful, and will never take one step or one look in my room. They always ask me, "Why don't you like something else like a dog or a cat?" and they always tell me my snakes will get huge and try to contrict me one day (trying to scare me and make me give up my snakes..).

At an elderly home, they may also be fearful is getting sicknesses and they may think your snake will carry all kinds of diseases. If you do have it there, it would be best to just not show the elderly the snake at all, and also not talk about it around them. Then they may go crazy that they think there's a snake in the building
