I sing a song to my cat all the time...
"Elwoods a pretty boy, yes he's a pretty boy, and all the cats around the town can't compare to the prettiest boy"
When my brother and I were little my mom had songs for us. My name was sung with the kit kat jingle to it and my brother had his name sung with the Davey Crockett theme song.
Do you ever sing a song to your kids or pets?
