Beautiful Kitties!
We have 3 feral cats that we care for. All have been fixed and given shots thanks to a wonderful organization here called Heaven Can Wait. HCW is part of a city wide program here in Las Vegas to help curb our huge feral population. They have volunteers that trap the ferals. The cats are then spayed or neutered, given their shots, groomed if needed and then returned to the area where they were trapped at. The cats all have their right ear tipped so the trappers can tell which cats have already been through the program. There are many "colony caretakers" around the city that feed the ferals, and trap if medical care is needed.
The female cat we call Mama lives on our patio and never leaves our back yard. She is very loving, will sit on our laps for pets every time we go outside. The 2 males only show up at the evening feeding time and leave after they have eaten. The males want nothing to do with people and go out of their way to stay very far away from us.
