My mother actual prefers that her grandchildren are dogs and a cat. Mom said she was at work one day and she said something about her grandkids and her co-workers looked at her and told her she couldn't be old to be a grandmother. After she thanked them and told them that technically she is because her oldest is 27 and her youngest is 19 her grandkids have 4 legs and fur. Dustin's mom calls them her granddoggers, which everyone thinks she says granddaughters. She's gotten quite a few people like that.
