I'd be very upset if this happens but why would an owner put a dangerously larger pet where it can reach another that's particularly more vulnerable? Whenever I see videos of birds and cats being close to one another, this makes me nervous, especially if the birds are parrots and cockatoos. I know it may seem adorable if a bird starts playing with the cat that looks like it doesn't want to be bothered but one has to consider the risk here. Larger animals were known to have turned on to their owners or caretakers and end up killing them. I would not be surprised if a pet kills another pet.
