Oh Kim, you're certainly in a difficult situation, but I agree with the advise you've got so far. I don't know how long you've had the cat inside, but it takes a while to tame a cat - I know from experience!! I was very resistant when we first got Fister up from the yard and would let him out at the least sound of complaint. I do think that forcing a cat is quite impossible - and wrong, but with patience you may succeed. I wish you the best of luck!
