I love the contest idea, that sounds wonderful. Also, if you don't like any of the names submitted, you could always just add a card or two with your own name choices in the box...just in case.
I know, it's wicked of me, but having asked
my kids to help name our pets in the past, we've gotten some ummmm "interesting" ideas. In fact, we have a 9 year old, huge 15 pound male cat still named "Gray Baby".
It's always good for a smile when we go to the vet with our behemouth cat with a kitten name.
So anyway, I really love the idea of getting the kids involved, but that would give you a fall-back plan, too. Please give that sweet baby lots & lots of kisses for me.
