We rescued two (Lazlo and Sheldon), then rescued a third (Munchkin). We care for lots outside, and have gotten three of them adopted - two have already gone to their new home (last week. Yay!) We actively practice Trap-Neuter-Release (TNR) despite having other full time jobs.
For those of you who feed outside cats, you should consider talking to the Landlord about trapping them in order to stop the proliferation of unwanted cats, which will be a problem for the building and/or area whether you feed them or not.
Low-cost spay/neuter resources are available at SpayUSA
. You can also simply call a local Vet to ask about local low-cost programs (of which they would be aware.)
Hints on trapping are available in the Ferals & Rescue forum of this site Trapping Cats and Kittens
...and if the only problem the landlord has with feeding the cats is the containers, you can check out feeding options and suggestions at Alley Cat Allies, an organization devoted to aiding feral (wild) and stray cats: Alley Cat Allies
. The site has feeding information, as well as "leaflets" with arguements you can provide for the benefit to your community for caring for these cats.
