"I can't afford it"
I was just speaking with a volunteer who called up to complain about the dumping going on in her area. She said that she knew quite a few of the people dumping, and had in the past often gone and offered to sterilise and transport the cats for them. However she said, while they were open to the idea of sterilisation, they would not pay for it. She ended up paying for quite a few of the cats. In the meantime, more people are picking up cats, and also refusing to pay, or letting their existing cats breed till there are too many, before they dump the cats.
This is a perennial problem. Also not all these people who claim they cannot pay are really unable to do so - it's just that they don't want to pay for sterilisation. This caregiver agreed that many of them looked quite comfortable and were not badly off.
She said glumly that the vacations are coming up which is going to lead to more dumping. Town Councils on the other hand and the HDB don't want to tackle this problem of dumping - all HDB will do is tell the residents to get rid of the cats. Guess where these cats will go?
We once toyed with the idea of setting up video cameras or webcams in estates so as to catch some of these people in the act of abandoning the cats. It seemed a bit pricey at the time - but it might be a good idea to look into it again. This could of course also be used for abuse cases. The problem would be of course how best to situate the camera.
