My daughter's kitty was abandoned by mom at a couple weeks and fed by eyedropper by owner until we scooped her up at 6-8 weeks. To the day she died, she kneaded and sucked on the comforter on my daughter's bed, very blissfully. When my daughter was too old for a Sesame St comforter, we kept it out in the playroom for Cuddles to enjoy.
Thanks be, she never sucked on necks or ears or other interesting appendages because this cat lived THIRTEEN (blanket-sucking) YEARS!!
