My new cat, Tweaker, went to the vet last week, and now I see he has
developed a callous between his shoulders, and the skin there is
tender and raw.  I suppose this is an antibody reaction to one of the
vaccines.  Is this common?  Is it a problem?

He is the sweetest of cats, BTW.  He always wants to be in my lap and
he puts his paws on my shoulders and hugs me.  He is a pest, forever
getting into stuff, and he harrasses my dog (who could crunch his
spine like a milk bone if she wanted to), but we both love him to
death.  He always keeps his claws tightly pulled in and his play bite
is gentler than any cat I have known.  He is tiny -- about 4 lbs I
would guess.
