Awwwwww, they are just adorable.
We had an accidental litter years ago (mummy car was very poorly and vet suggested a spay would be risky).
She got pregnant (my Dad took joy one morning in shouting us to come and see while she did the dirty on the lawn, whilst my mum ran out shouting 'get it off'). The inevitable kittens arrived and we all loved every minute of it (apart from the re-homing, still have me sobbing on video camera aged 10).
I love when they get to about the age yours are now & they start reaponding to you. Ginger is my absolute favourite, I had a very very special ginger boy who I still miss dearly.
