I don't see the purpose of cats. Dogs can protect you, can sniff out things, and can be your eyes if you're blind. Could you imagine a seeing-eye cat? The first person who walks by with an untied shoelace, and you're history.

Framed as a comic comparison between cats and dogs, the speaker argues that dogs’ usefulness (protection, scent work, service-animal guidance) gives them an obvious “purpose,” while cats’ value is less utilitarian and therefore easier to mock. The punchline—imagining a “seeing-eye cat” that would trip its blind handler over an untied shoelace—leans on a common cultural stereotype: dogs as loyal helpers versus cats as indifferent or mischievous. The humor depends on exaggeration and anthropomorphism, but it also gestures toward a broader theme: how people justify affection for animals by assigning them roles, and how companionship that isn’t “useful” can be undervalued.
