It is an anthropomorphic comic set in a world based on hunting and predation. Kevin & Kell is about (and named after) Kevin Kindle (a rabbit) and his wife, Kell Dewclaw (a wolf), and their family.
Kevin & Kell is not the oldest comic strip on the Internet, but is the first strip syndicated online. It began as a feature on CompuServe before moving onto Bill's website at http://reuben.org/~holbrook. It is now a feature on AOL's ToonVille service.
and has two other websites dedicated to it - Herdthinners, Inc. and Kevin & Kell
The backstory: Two lonely people - he was divorced, she was widowed - met in an online chatroom and fell in love. He discovered that she was a wolf. She discoverd that he was a rabbit. They married and started what could best be described as a mixed family.
Kevin, Kell, and the most of other major characters live in the city of Domain, which is roughly analogous to Atlanta, where Bill Holbrook lives.
Significant characters include:
Kevin Dewclaw (nee Kindle - he took his wife's name) - A rabbit in his late 30s. Formerly a Forum Manager at an ISP remarkably similar to CompuServe, he is now the sysop of a local ISP, Harelink.
Kell Dewclaw - Kevin's wife. A wolf in her mid-to-late 30s. Recruiter at Herdthinners, a hunting corporation. She has held a variety of positions at that firm, including hunter, webmaven, and manager. She eats meat but is generally vegetarian, especially around her husband. She is named after the Book of Kells, a Celtic manuscript from the 8th Century AD.
Lindesfarne Dewclaw - A hedgehog. Kevin's (adopted) daughter from his first marriage. Approximately sixteen years old. Amateur scientist. Insectivore. Named after the island of Lindisfarne, off the coast of England.
Rudy Dewclaw - Half fox, half wolf. Kell's son from a previous marriage. Member of the Caliban High School hunting team, competing in mixed foursomes. Age 14.
Coney Dewclaw - half wolf, half rabbit. Kevin and Kell's daughter. Carnivorous rabbit, age 2. One of a very few mixed-breeds in their world. As a result of this, she is regarded with suspicion and hope.
In 1999, the strip began running in color. It is coloured by husband and wife team Terrence Marks and Isabel Marks, who are also online cartoonists.
In addition to running online, the strip is available in book format through Plan 9 Publishing. There is also a Kevin & Kell comic book, unavailable as of October 2003, "Origin of the Species".
