Kaya is a cat shaped like a jar of kaya (that is how I got the inspirationšof the character), the coconut jam we love in Malaysia.
Round, orange, and permanently unimpressed, he guards the sacred ritual of the slow breakfast, coffee, half-boiled eggs, and toast done properly or not at all.
He judges anyone who orders takeaway, naps on the till during rush hour, and has never once moved for a customer.
In Malay, "kaya" means coconut jam, and also rich. He is both.
