I am so sorry that this is happening to you and your cats but very upset hearing how your father and brother are acting and treating you and them! All I can say is to just keep doing your best, and as for them, well, one day they will have to pay for their lack of sensitivity towards animals and you, as Jesus said "inasmuch as you have done it unto the least of these you have done it unto me".
Stay strong and keep your love of animals, maybe someday they will wake up and learn to love them too!
