I just met this cat a while ago - a group of people are trying to start up a programme in their area. The problem is that apparently a lot of people are feeding them and the number is exploding. The other problem is that while they just started the programme, it seems as if the management of a building nearby just started putting out traps.
There are quite a number of cats there - I managed to speak to someone who is a tenant of the building, and she will get us in touch with the management.
One of the women I spoke with mentioned that they'll get the cats sterilised first, and worry about the rest later. That's a good approach to take if your idea is to control the population and it's certainly laudable to sterilise, but it's not so good if your concern is the welfare of the cats in the long run. Adoption as was suggested by one of the woman, is not going to be an option for most of these cats. Another agreed and said that they would definitely need to be returned.
