The man is the owner of the cat, Maya, and is humorously explaining the cat's peculiar grooming habits related to human body odor and how cats perceive smells. The cat is present and visible next to him.
Isn't that a little too much of a close-up shot? Yeah, when my French friends visit, and if they expose their armpits, my cat will definitely groom those with the strongest body odor. But Maya seems truly happy when she's doing that. He was diligently grooming, giving his absolute best. You know how cats sometimes sniff their owner's shoes, especially when they come back from a hike, and react with that Flehmen response to the foot odor? They can gather various pieces of information through their sense of smell that humans cannot perceive.
¿No es un primer plano demasiado cercano? Sí, cuando mis amigos franceses vienen y exponen sus axilas, mi gato, sin duda, acicalará las del olor corporal más fuerte. Pero Maya, verdaderamente, parece muy feliz cuando lo hace. Estaba acicalándose diligentemente, dándolo todo. ¿Sabes que los gatos a veces huelen los zapatos de sus dueños, al volver de una caminata, y reaccionan con esa respuesta de Flehmen al olor de pies? Ellos pueden captar información a través de su olfato que los humanos no percibimos.
