Thanks so much for all the advice everyone 
I will indeed look into free range organic chicken wings.
Rose both our cats were rescues who'd not had much handling as kittens at all, you see, the poor mites. If I were starting out with a kitten I would definitely do exactly as you did.
It took a while for our two to settle, and even now 3.5 months later it's not always hunky-dory. Little black cat doesn't like being handled at all (picked up) but will come to me for rubs. Coley is a bit of a ruffian has emerged as top-cat. She's never sat on me. She's a brave, spiky little character who guards the garden from interlopers that are much bigger than her! She loads of love in her but doesn't really know how to express it apart from lots of little love-bites.
Margot does like a cuddle and contact, she doesn't mind being handled too much. She has a really sweet personality, and you can feel she's doing her best. Doesn't like Coley much but there you are.
I feel sad for them sometimes, thinking of their little kitten selves with no love. But then, I reckon they are content now, have their own family and garden and home so yay for that!
Enough soppy wittering out of me! Chicken wings!!
