Don't do it for her: do it for the bird. It's the BIRD that needs your help.
I don't know all the details surrounding this but if there is something you CAN do then DO it. I honestly don't give a flying fuck about your grandmother: she can rot in hell for all I care and I'm sure you feel the same way. What I care about is that bird and even though it's still her bird and you can't force her to rehome it (unless you can convince your dad in some way that it's for the best), there are still a few things you can at least try such as simply swallowing your pride and asking her directly to let you find a new home for it (at the VERY least get her to agree to let the bird go should the time come that she can no longer feed it/water it/clean up after it ect) with the soul intention of caring for the bird's well being. If she truly cares about that bird (and you don't let your hate get in the way) then she'll agree and you can start finding a better place for it. If not then pay close attention to the state the bird is currently in because at a certain point you (if you don't mind being a little underhanded) should be able to have the bird taken from her on the ground of neglect (or at the very least once she's no longer able to feed it and such) and then go to the shelter and officially adopt the bird there: that way the bird becomes YOUR'S to do with as you wish and what you wish is to take care of it until you can find someone who's more able to/willing to take over.
All and all, I feel like simply sitting down with her and having a heart to heart with her will get the job done but you HAVE to detach yourself from how much you hate her or it's doomed to failure right from the start: you can go back to openly wishing for her death, afterwards but until then you need to go in with the willingness to say or do anything to convince her that the bird is better somewhere else.
i am not going to break into her house to relocate her pets, one thing that has not gotten across is that if i was to need to relocate it, that is my only option to do so, this is not something i am willing to break the law for
she likely does care about it, but like with her v8 juice, her disregard for money, and driving when she cannot know whos dog she is walking for a short time, she is unsuited to make choices, but thats my view, not something that can be forced
ar the moment, the bird is not in danger or at serious risk, as far as i know, what has to happen os her to keep track of her medical stuff, check her blood sugar, and keep stuff updated with doctors, for that she needs the computer to work, and thats what i asked
i don't belive she will remember or care enough to lock the computer parts away each time, even if my dad(after this was first posted) thinks the bird won't destroy this keyboard because its not as easy to get around the keys
i have 0 ways i can change her behavior, thats core to all of this, i have an extremly limited ability to alter the conditions around here, and that is what i am asking about
