Where can I get cheap service to spay cats? I got a couple of stray cats which have been hanging out around my house. My mom has been feeding them daily. 3 generations. The mum gave birth to a couple of which 3 still survives. And out of the 3, 2 gave birth recently and even the mom gave birth as well. So I'm guessing there's about 20 cats and kittens or so in or around my house now including 5 of my own cats(which have been spayed). So I was planning to spay the cats(if I can catch them) that are around my house. Any idea where I can do this cheaply as there is quite a number of them.

Hmm, quite costly. I think I called SPCA in Ampang and they quoted me 90 for castration and 110 for spay. Might go there.
