Well, I do keep in touch regularly with the store owner of the place I got Nagini and Mystic from since he's also my 'pre vet' consultant on herp health.

As for other rescue or adopted animals I've had, it all depends on the circumstances of why I got the animal. If it was to help the person out, then I certainly would stay in touch. If I was getting the animal away from bad conditions, I would never want to see that person again.
