You kind of have to hold them long enough until they start pretending to cuddle with you. I call it "force cuddling". It sometimes works.
*Side note: Will post dates and details of my book signing for CvsH soon. I have 2 going on in the Bay Area (one at Books Inc. in the East Bay and one at Book Passage at the Ferry Building in SF), and another signing in Changing Hands Bookstore in Tempe, AZ. Email me at catvshuman @ gmail . com if you have any questions :)
