Hardly, since that's already been tried....more than once.<quoted text>There used to be a feral colony under the house next door. Cats roamed this neighborhood at will, and this one guy up the street would NOT stop feeding them...three times a day, every day, for years. He left town for a couple months last year, and they all disappeared. Took him about 6 months to get new ones.
Quit feeding it.
(Worth a shot.)
Yes 99% move on. It's the remainder that become the cockroaches in an apartment complex. Exterminators just chase them from one unit to the next.
