Well that's impressive, the few experiences I've had with feral cats weren't good.
Kittehs just wuv you!
It can take a looooong time to do it but I’m patient. The key is getting the cat to stick around long enough to see me playing with the other cats outside. That lets it see I’m not gonna eat ‘em. LOL! It slowly loses its fear and eventually lets me touch it. Once it discovers how nice it is to be scratched, it’s hooked and the process speeds up immensely.
The vet calls me the Cat Whisperer. :-)
