i been looking for a cat also, miss my cats back home.
But your right its expencive here..3-8K for a cat.
I actualy found a really ugly one today it had a serious underbite, but it was so friendly and it has so much personality that it became my favorite right away, i really want it..but 6000
i just cant fork out that much at the moment, then again i would try to buy almost any cat or dog in hk to save them from those horrible cages some are keept in.. breaks my heart to see them like that, my rabbit has a bigger cage than they have :S
