Must be something in the air.... Jack always sleeps with DH and I. He usually starts out by DH and then cuddles up real close to me. When I get out of bed in the morning, he will cuddle back up to DH. Yesterday I was getting ready to leave for work and I always lean over, give DH a kiss and then kiss Jack. Well, wouldn't you know, as I was leaning over to kiss DH, Jack jumped up, growled and showed his teeth to me....
I really wanted to smack him, but instead said "bad boy!" DH thought it was cute - said Jack was protecting him...I think Jack was mad that I had to leave.
Any way good luck with the little stinker - that is one thing I have found, sometimes I swear Jack does things on purpose... but they truly are cute and you can't stay mad at them longer than a nano second!
