A valid point.
My family has concerns about me living in squalor surrounded by animals that are kept in rotten conditions because the collective workload and financial responsibility is too much for me to handle. They've raised further concerns about "how on earth are you going to manage to move somewhere else when it's time? Are you going to take them with you?" (I've already moved with them once, along with a much more difficult to move aquarium, and that's why I installed wheels on the rack of course!)
I think that's a valid concern in respect to acquiring numerous animals of almost any other type so you can't blame'em I guess. Best not to throw kindling on it though.
