Cat Shit One (Japanese: キャットシットワン, Hepburn: Kyatto Shitto Wan) is a three volume manga series written and illustrated by Motofumi Kobayashi. It was published in North America and the United Kingdom (printed in Canada) in 2004 by ADV Manga. It was also released in Poland in 2006, also under the title Cat Shit One. It has been released in France, Belgium and Spain, as Cat Shit One, by Glénat in 2006.^[1]

In 2008 Kobayashi released a follow-up to Cat Shit One – Cat Shit One 80. Currently four volumes have been published in Japan.

A computer-generated original net animation series of Cat Shit One by Studio Anima began release on IDA Entertainment's YouTube channel in Japan from July 17, 2010,^[2] and in North America, Australia and New Zealand on February 5, 2011. The animated version is set in the Middle East rather than Vietnam,^[3] and a trailer indicates that the action takes place after 1991.

The manga follows three American soldiers (who are anthropomorphic animals) in the Vietnam War named Botasky, Packy and Rats. All three are in the recon team called "Cat Shit One". Each mission (or chapter) shows the daily activities of the reconnaissance group in Vietnam. There are sections of the manga which give brief history and truths behind the war, such as the types of weapons used by different countries and the activities of forces in the war. At the end of volume one there is a chapter called "Dog Shit One"—separate from the main story—showing human characters.

In Cat Shit One '80, the story continues to follow the three main protagonists as they became involved in various low-intensity conflicts in the 1980s. Perky, now a member of the elite Delta Force, was attached to the Special Air Service and was involved in various SAS operations while Rats and Bota were involved with the US operation in Afghanistan against the Soviet invasion.

An animated adaptation of Cat Shit One was released in 2010 and set in the 21st century Middle East; however, it follows the Cat Shit One '80 storyline.

The manga depicts the characters as different animals according to their nationality as follows:

• American – rabbit (from the Japanese word for rabbit: Usagi ("うさぎ"): USA G.I.)
• Vietnamese – Siamese cat
• French – domestic pig (from pigs used to hunt truffles)
• Chinese – panda
• Japanese – Japanese macaque and gorilla
• Russian – brown bear
• Korean – nureongi (from the dog dish bosintang)
• British – rat (from The Desert Rats)
• Australian – kangaroo and koala

The following are new animals depicted in Cat Shit One '80:

• Botasky (aka Bota) Voiced by: Satoshi Hino (Japanese); Tom Flynn (English)

After the war, Botasky made a fortune selling fast food and became the chairman of a multinational fast food chain.

• Beckwith

Major Charlie Beckwith, the commander for the Special Force Detachment B-52, is in charge of the recon team operations. Cat Shit One always receives their orders directly from Beckwith himself. In Cat Shit One '80, Beckwith becomes the commander of Delta Force and is forced to retire due to the failure of Operation Eagle Claw.

• Misha

Introduced in Cat Shit One '80. Misha is a young brown bear that is an inexperienced Soviet VDV second lieutenant sent to Afghanistan to reinforce the Soviet forces in the region. His position was under heavy suicide attack by the Taliban, and he was rescued by Perky and a small SAS detachment. Due to his bravery, he was assigned to a Spetsnaz unit. It is later revealed that Misha is the son of a high-ranking KGB general.

The recent Cat Shit One adaptation was nominated for Outstanding Achievement in an Animated Short category in the 9th Annual VES Awards.^[7]
