Is there more cats in the world or is there more dogs in the world?

As a keen observer of financial markets and trends, I often find myself pondering over intriguing questions that intersect with the world of cryptocurrencies. One such question that has recently piqued my curiosity is: "In the vast landscape of pet ownership, which reigns supreme - the feline majesty of cats or the loyal companionship of dogs? Is there a greater population of cats prowling the earth, or are there more dogs wagging their tails across the globe?" This question, though seemingly unrelated to the world of finance and cryptocurrencies, nonetheless presents an intriguing comparison of two vastly popular yet distinct entities. It begs the question: what metrics should one consider in answering such a seemingly simple yet complex query?
