Stray cat lai kata lagney

Couldn't get a better picture because it doesnt stay still .

Since 3 days, A cat (pretty sure its a female) has been welcoming itself in our room. It yells and meows when we lock the door and keep it outside . I would keep it but my mom doesn't like pets. Rati pani dhoka lagayo vanera karako karai garxa. Its a stray so i don't know what it may do. It may pee and poop on my bed or sth which i dont want. I did feed the cat some biscuits but my mom is very against it. So please kindly help me by providing info on where to take it. And by where i mean a rescue centre or sth idk .
