That's an interesting thought... however, instead of them being called homes, they should be bases. Like a pirates secret base.
And as for a pet idea... that wouldn't be to bad, I'm sure the first idea for a pet would be a parrot.
Anything's possible.
However, I think you might just live on your ship. (if you have one) But having a secret base/home wouldn't be a bad idea.
