Sure, my pets names aren't used as a security question anywhere so my cat's name is legally Meerkat but my grandma called her Kit-kat (I inherited her after both of my grandparents passed). I call her "little baby meow meow boo" bc I am a dancegavindance/Jon Mess fan.

I also had a boxer I think about everyday that we called Nevada and I loved telling people her name when she was alive. She was born in Nevada and belonged to a member of the Washoe tribe when I got her. Her full name, Running Acres Nevada Sunset.
