Does anyone else care for a feral colony ?

Does anyone else care for a feral colony ?
For decades the only option for people like me who were feeding feral cats and wanted to do the responsible thing and keep them from reproducing, was a process called T/N/R.
And then in a chance Google search, I found the FeralStat site. I could hardly believe what I was reading. A non-profit in Connecticut could prescribe a powdered birth control which could be added once a week to wet cat food and, after two weeks, would prevent female cats from becoming pregnant.
