The film lacks explicit LGBTQ+ characters or non-heteronormative romantic arcs. The central conflict involves a traditional marriage arrangement, though the story focuses on rejecting that arrangement.

Haru's arc disrupts conventional female passivity by reclaiming her autonomy. She subverts the damsel in distress trope through psychological resilience and a refusal to conform to gendered nobility expectations.

Traditional human racial hierarchies are bypassed in favor of a fantastical realm. Anthropomorphic characters serve as metaphors for social stratification rather than ethnic identity, departing from Anglo-centric casting norms.

The Cat Kingdom critiques institutionalized conformity and rigid social structures. The narrative prioritizes the individual's true self over the preservation of traditional societal roles and systemic pressures.

There are no prominent depictions of physical or neurodivergent disabilities. The plot focuses on the protagonist's psychological journey, leaving little room for exploring visible or invisible disabilities.
