Under attack

Benji ! Our new family member.He is gorgeous ,loveable affectionate ,courageous,cute and generally a joy.But how can something so small,something so cute be so god damn vicious??? I am covered in tiny little puncture wounds.The object of his attack instinct! I ahve placed toys all around the house for him so that he doesnt get bored and has plenty of outlets for his kitty energy but still he comes back to the bare flesh...........
