I have two 13 week olds (bouncingly recovered from the flu) who have been with us nearly a month. Kitten 1 mostly manages to adore us without claws. Kitten 2 is equally affectionate but sinks his claws into our arms, legs and neck, all in the cause of love (or food). They get a good lot of play (not with our hands) and fight together a lot, but they are also both very keen to be close to us. I try to remove myself from no. 2 when claws come out but I'm usually trapped at sink or keyboard - any other suggestions? He is due to be neutered next month so might that help?
