Congratulation on your new baby and also I'm sorry about little Gizmo....
Seems like you got one healthy boy!!!
It isn't too late to change name!!
My Momiji is a little "piranha" herself.
Just like sweetsnugglie, I use bitter apple spray on any electronics cord and she stop biting.
Luckly she hasn't bite much of the furniture yet but she sure loves my finger!!!!
