Does your pet sign greeting cards?
I usually only have my calico cat, Julie, sign when we write to others who have cats, or who know and love Julie. And I have one neighbor who just sent me, same as she does every year, a Christmas card addressed to Julie and me with a loving message to both of us inside. Cracks me up because we live in the same apartment complex, yet my neighbor puts a stamp and mails the letter so it will come to me through the post office!
Happy Holidays to all from Martha and Julie!
