Cuckoo effect: covering the kitten's eyes, it reacts by emitting sounds that simulate sadness or fear, and, removing the hands, the kitten returns happy, emitting sounds of contentment.
Nourishment: The kitten "eats" the fish when it is brought close to its mouth, simulating the act of eating realistically.
Care and Pampering: stroking the kitten's head, it emits verses of happiness, thus stimulating emotional interaction.
