I have a few cats of my own but one day a big Feral Tom Cat started to visit the garden,..i tried chasing him off to no avail,..he would stand his ground,..i decided the best option was to make friends with him,..it took three months before he would allow me to hand feed him or stroke him.
As time passed he sired a litter of kittens and surprise surprise he would lie down with them while the mother cat was away,..apart from some pictures of him there is a short video,..if you turn up your sound you will hear him.
The second last picture is one of his offspring.
