About a year ago we found this baby stray/ feral kitten. Since we were on holiday and it was just too small to take it on a plane, we couldn't keep it. The only solution seemed to give gave it to a mother cat, who gently took it with her.
Still wondering if he has grown up to be a health and huge cat now......
BTW, it's not actually my finger, but my -at the time- bf's. For the full story:
When I was a boy, we had a kitten who did the same thing. When he grew into a huge (20+ lb., no fat) adult black & white tomcat, named appropriately "Menace", he would do the same thing, only around the forearm, still playing, without claws extended. He would hunt wild during the summer, and come home for the winter, right up to his final disappearance at the age of about fifteen.
