My cat has been missing for 3 days and I don't know what to do
I'm 16, I have a 1 year old cat and my parents let her outside every day despite me not agreeing. She used to be strictly indoors for months. Now the cat jumps out as soon as a window is slightly open. It is impossible to keep her inside and my parents won't even try. She goes out for hours and doesn't come back until late at night (2-3am). She is very confident and always approaches people.
For 3 days she hasn't come home. We also live near VERY busy roads. There is an airtag on her that shows she's been going to private areas that we can't access, and I think someone is feeding her which is causing her to not come home at all. (She also poops outside, never uses litter box anymore) No idea what to do. Last night her tag showed she was on a very busy road and not moving. My parents went out with a trash bag just incase but didn't find her. She has been moving to different places since then. My parents aren't really bothered
