I finally located Lovey - she reappeared on the stovetop, thank goodness I'd not been cooking anything. I quickly zapped a raisin in the microwave, cooled it outside and then pointed her to it - she happily crawled on and fed.
I did not have a chance to tell my Mr. that this was "Lovey's Dish" and when I woke this morning and found the dish empty, and knowing the raisin was bigger than Lovey and she could not possibly have eaten the entire thing) I asked my Mr. if he knew where Lovey's raisin went to. Ahem - he got an alarmed look on his face and he confessed he ate the raisin - went nicely with his granola breakfast! I hope he does not get sick.
Then Lovey disappeared again - I finally located her snugged up in a corner up by the ceiling, sleeping off her full tummy.
