My cat is a rescue. He was about a year old when I got him and in a lifetime of cat ownership I have never come across such a terrified wee thing. For the first week he hid under my corner sofa, out of reach, and only emerged to pee or eat when I wasn’t around. Two years on he is a different cat who occasionally deigns to sit beside me and allow me to stoke him while he purrs loudly. However, he still runs away from everyone else, including my daughter who is also a cat lover.
He is an absolute hunter but never kills his prey, just brings it into my bedroom in the wee small hours, charges around the room until I wake up, then releases the darn thing. Cue for me to leap (I wish) out of bed and endeavour to catch the mouse and return it to the garden. He just sits there all neat and composed and watches.
I wouldn’t change him for the world.
