Do cats stutter?

A teacher is explaining biology to her year 4 students. "Human beings are the only mammals that stutter", she says.

A little girl raises her hand. "I had a kitty-cat who stuttered."

The teacher, knowing how precious some of these stories could become, asked the girl to describe the incident.

"Well", she began, "I was in the back garden with my kitty and the Rottweiler that lives next door got a running start and before we knew it, he jumped over the fence into our back garden!"

"That must have been scary!" said the teacher.

"It sure was!" said the little girl. "My kitty raised her back, went 'Sssss, Sssss, Sssss' and before she could say "Shit", the Rottweiler ate her!
