Spay/Neuter College Point Ferals

You may have noticed all the feral cats in your neighborhood. Breeding season is coming up and if these cats do not get fixed they multiply extremely fast. Think about it, if one cat has 5 kittens, then those 5 kittens have 5 kittens each that is already 25 - now those 25 each have 5 thats 125 etc. Please help in any way you can, as little as $5 can make a big difference.  I work in College Point near the water & there are several colonies that need to be fixed. Last summer I got 11 cats fixed with 4 kittens adopted. I'm raising funds not only for their spay/neuter ($35 per cat) but also for food and medical supplies. Thank you in advance for any help & if you can't contribute could you please share.
