Kitten is the placeholder name given to an as yet unnamed kitten who's a friend of Martha.
Kitten is very friendly, rubbing up against Martha and purring (apparently she reminds him of his mother), and quick to forgive people (or dogs). He is a bit naive, seeing as he nearly crossed the road without looking first, so Martha taught him how. He doesn't have a mean bone in his body. He is also a bit shy, so before he was adopted to the house he lives in now, the Boxwoods (with assistance by the Lorraines, Martha, and Martha's dog friends) helped him socialise with people and dogs.
Kitten is about the size of Martha's head. He is a ginger longhair.
