No, it is you who are in pain, dear Andrea.  You are worrying way more than you should and you are making your dear little creature nervous.  You need to relax and enjoy this wonderful being that has come to teach you about unconditional love.  Just enjoy this warmth, this dear one.  It’s true they sometimes have difficulties, but these amazing creatures have learned to heal themselves much better than the human can.  Trust that this little cat is fine and not in pain.  It pains the little one when you are in pain.
