hi friend! i own snakes in a home that's not entirely well-receptive to them but we make due.
i moved back home after i changed jobs, and i had already had my first ball python. but i have 7 snakes now and am independent, and i take care of my home as my parents aren't normally home. i clean, buy groceries, and tend the pool and garden. i don't do this for fun.
the thing is: you have no weight to sling here. you're broke, don't provide any monetary support to the home and likely don't support anyone else in the home. you have no right to sneak something in without giving back to your home. period. you don't get to force an "independent" decision on a house you provide nothing towards. that's purely selfish and, again, unfair.
it's not us being harsh, it's reality. if you can't accept the stakes of what can happen if this goes wrong, and would rather throw a tantrum, then the long-term decision of owning a 20yr+ commitment pet when there are obstacles to it may not be best for you.
we're very happy to have you, but to force this into a home you don't support is just not fair.
