The message I replied you was gone by me mistakenly pressed the ESC key. I can only reply you in English.
You cat remembers you well. She is just "ANGRY" with you as you put her "away" in someone's house.
I got this terrible experience when I give away my first cat to a friend. After one month, I went to visit my cat, he totally ignores me. He even changed the way he "meows" ... very sad.
If you have time, go and visit your cat as often as you can. Bring along something she likes to eat (叫為食貓是有原因的). Pet her and talk to her, telling her that she will be home soon.
Of course cats don't understand what we said but she can feel it. Let she knows that you are not giving her away. Cats are VERY sensitive animals and they are afraid of being "given away" by their owners. If they have this feeling, they will stick to their "new" owner in a short time ... and won't "forgive" you even tho' you want her back.
That is why people said cats are like women .... :cry:
