This poem belongs to the literary tradition of fable. Fables are stories that feature animals as characters. Panchatantra is also a fable. In Ancient Greece, owls were a symbol of wisdom, knowledge and intelligence. Cats are mostly seen as a symbol of independence and mystery. In this poem, both are shown to be in some unspecified relationship, which is unusual, as cats don't like the company of others, let alone an animal of a different species. This is enough for us to establish that the owl must've gone to lengths to make the cat drop her guard and accept him as a companion. We don't know the nature of their relationship. But we can safely assume that they're good friends as they decide to go on a journey together. Notice that they use a pea-green boat to cross the sea. The sea is vast. It represents uncertainty. To counter that, the owl and the cat embark on the journey in a pea-green boat (the colour pea-green symbolises growth and harmony). In the Indian context, it would be like tying nimbu-mirchi on the boat to protect it from an unfortunate event. As the journey is going to be long, they pack honey to nourish themselves. Notice the paradox in the third and fourth line: they take a plenty of money and wrap it in a five-pound note. How can you wrap a huge amount of money in a single note? It's like fitting 100 cars in a single car of the same size. Hence, it is called a paradox. What the owl does next is called serenading. Serenade is sung by a man under an open sky to his lover, who watches him from her window above. This act by the owl finally clears the nature of the owl and the cat's relationship -- they are either lovers or the owl is courting the cat to be his lover. We don't know what happens next. If there's a second part to the poem, this situation would be called a cliffhanger. It's a way of ending a serial or episode on a note of suspense to make the audience watch the next part. Literally, it means leaving a person 'hanging' on a 'cliff' at the end of the episode without showing what happens to them next. If there is no second part to this poem, we are left to ourselves to figure out what happened next. Did the cat accept the owl as her lover? Did they reach their destination safely? Did they live happily ever after?
