Y'know, Rebecca - if people show up with kittens to give you, I hope you are able to get through to them the idea to do what you did - for the mom and dad to invest in spaying and neutering for the cats around their place.
Kind of like a neighbourhood improvement tax!
There is a town somewhere in the USA - I forget which - where the trap/neuter/return program eliminated the stray cat problem.
A quote from one site:
Here is a link to a couple of places:

For a fraction of the taxpayer's $$, and with volunteers, neighbourhoods and areas can be totally feral-free...no new wild kittens.:)
Surely some folks in your area might get on board with this? And ask the nasty neighbours to donate? ;)
Think about it....:)
