he's so cute and fluffy!!
we got a longhair kitten when my daughter was 9. She named him "Fluff Nugget" because she said "he's a nugget of fluff". And now we have all kinds of nicknames, we call him Foofy, Fluffy, Mc Nugget, etc.
anyhow, my first thought for your GP was "he's so cute and fluffy!". lol. then again we're a bit non-traditional with our pet names!
