Grooty Fledermaus is the first book of seven in its series, and it is a children’s book. The story begins with Katie sitting alone, looking outside the window. She uses a wheelchair, and her mother thinks a trip to Grandma’s house may change things for this little girl. As her Grandpa shows her a batch of little kittens, she notices a different one. The kitten has no hair. She names the kitten Grooty Fledermaus and her adventures begin.
