Dad's workplace cats

These three cats are from dad's workplace that is a warehouse. The two older brother cats are due for sterilization next week and in feb. There used to be five siblings cats around but two died of poison and the third died of a fatal accident. Now, there are only these two brothers. The little black cat joined the two brothers suddenly one day.

From the picture, u will noted that the area is quite dirty... in fact, everything there are dull and black. It is really a bad condition to live in for cats... so far, mummy cat & big ah Ou had gone M.I.A after we had sterilized them....
