Feb. 22 was Cat Day in Japan, because "two-two" in Japanese can be uttered using an approximation of a sound that cats make. It's a typical pseudo-event, invented by the pet food industry, which is doing quite well by cats. In fact, it's doing better by cats than by dogs if you're talking about growth.

According to the Japan Pet Food Association, about 10.9 million dogs and 9.7 million cats are kept as pets in Japan. The pet-related market, including medical care, is worth about ¥1.4 trillion, but while the parity between the two species as animal companions is about equal, sales of respective food products is increasing more for cats than it is for dogs.

Dog food sales peaked in 2004 at a little more than 490,000 tons and has been gradually dropping ever since. Cat food sales in 2005 was much less, about 271,000 tons, but cats tend to be smaller and thus need less food, and at any rate, sales have been steadily increasing in the meantime. In 2014, the association says that a household with at least one dog spends on average ¥2,884 a month on dog food, while a household with at least one cat spends ¥2,996.
