kitty-cat who stuttered

[Genetic Defect]

A teacher is explaining biology to her 4th grade students. `Human beings are the only animals that stutter`, she says. A little girl raises her hand. `I had a kitty-cat who stuttered`, she volunteered.

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 yard 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 yard!
`That must`ve been scary`, said the teacher.
`It sure was`, said the little girl. `My kitty raised his back, went `Fffff, Fffff, Fffff`..And before he could say `F***`, the rottweiler ate him!!!
