It's a bit tricky to classify the poem as a single type, as it blends elements of several genres:
* Narrative poem: It tells the story of a peculiar, aging cat with a rich inner life.
* Character poem: It focuses on developing the character of the cat, exploring its thoughts and feelings.
* Descriptive poem: It uses vivid imagery and sensory details to paint a picture of the cat and its surroundings.
* Occasional poem: While not explicitly stated, it can be argued that the poem was written in response to a specific event or person, as Robinson often drew inspiration from real-life figures.
Overall, "The Old Gumbie Cat" can be best described as a character poem with narrative and descriptive elements. It's a whimsical and thought-provoking piece that explores themes of loneliness, aging, and the mystery of the human (or feline) soul.
