Furry Comic

Basically, a comic populated by Funny Animals, with varying levels from the simple Talking Animal level to the full anthropomorphization (sometimes abbreviated 'anthro' in the wide circle of Furry Fandom), with characters that look like cuter versions of escapees from the island of Dr. Moreau.

More commonly than not, Furry Comics have mammalian stars, probably because it is easier to anthropomorphize something that's morphologically closer to humans. Still, many of this kind of comics rely on animal behaviour humour as an easy source of jokes.

Although Funny Animals are an easy source of humour (Funny Animals, anyone?) and cuteness, it's an easy target for Rule 34 (if not a consequence of it), to the point that fans and authors of innocent Furry Comics might get really offended about the sole mention of it.

Common tropes associated with this kind of strip: Non-Mammal Mammaries, Furry Confusion, Carnivore Confusion, Animal Stereotypes, Furries Are Easier to Draw.

A-E

Albedo: Erma Felna EDF
Apocalypse Meow [1] aka Cat Shit One: Covers The Vietnam War in all its horror but replaces the various sides with Talking Animas, the species apparently being selected based on common stereotypes. Cat Shit One is a special ops unit of American GI rabbits who have to carry out various strategic objectives in the steaming jungles of 'nam. An Animated Adaptation is being planned with the setting updated so that it takes place in the Gulf War.
Associated Student Bodies: Similar in format to Circles below, ASB deals with a young college lion inadvertently shacked up in the campus' gay-oriented dorm room, and his issues with dealing with all of the crazy characters he finds there as well as the conflict between his strict religious upbringing (and those of his family) and his budding homosexuality. A bit more sex than Circles, but it's still considered one of the best comics in the fandom to deal with real issues with the gay community.
The Astounding Wolf Man: A 25-issue series by Image comics written by Robert Kirkman. Adventures of a werewolf superhero.
The Black Blood Alliance: A pack of dire wolves must fend off a pride of saber-toothed cats.
Blacksad: A French-Spanish comic book about an American cat named John Blacksad who is a private investigator in the 1950s.
Build Tiger: An erotic bara//comedy doujin written by Gamma.
Circles: An ongoing gay-themed slice-of-life comic book. Word of God has said that it is a case of Purely Aesthetic Species. Oddly notable for the ads for porn in the back cover, a former pornographer as the main artist, being distributed by a company known for porn, but thankfully not actually being porn. There is plenty of fanservice, however.
Dracula is a straight adaptation of, well, Dracula. The furry aspects are only in the artwork, while the plot follows the original rather faithfully—which sometimes causes interesting questions like why a coyote would need to shave.
The End of Things: A furry comic about three friends in their last year of college, all of whom are struggling to figure out where the fit in the world, and one of whom has more problems than he lets on...
Eternity Street: Dinosaur Comics with foxes who are engaged in a domestic relationship!!
Evon: A comic about a young and developing sorceress named Evon. Living in a world that is a combination of Ancient Roman and Medieval society, Evon travels the world with her friend, Herodotus, fighting all odds to escape from the people that mean her harm and to uncover her past (more exactly, she pays him for protect her from a powerful mage).
Exterminatus Now: Sonic-like characters working for the equivalent of the Warhammer 40,000 Inquisition. And yes, they use the line.
Extinctioners: Another superhero-based anthropomorphic comic, this one taking a more serious approach than Supermegatopia below. There are several portfolios that the creator has pumped out, including many "Women of Extinctioners" pinups, three tutorials demonstrating how he draws the species in his comics, and—most recently—modifying existing superhero action figures to create toys of his characters.

F-J

Fuzzy Things: A comic about the adventures of eight kids on a planet both mundane and futuristic. It started life as an action comedy with occasional bouts of seriousness before pressing the Reset Button and becoming what it is now.
Guardians: [2] is a comic about wild cats gifted with elemental powers, using them to defend the world and overthrow the resident Evil Overlord. A perfect example of Panthera Awesome and Scenery Porn, but sadly, is not updated often.

K-O

Lost Opportunity
Morefuyu is a Doujinshi of Morenatsu.
Mudpie by Guy Gilchrist is noteworthy for being possibly the only syndicated comic to fit this bill. Starring the titular cat boy and his sister Punkin (emphasis on the "punk"), it ran as "Mudpie" in dailies and as part of the children's comic "Night Lights and Pillow Fights" on Sundays. Both appear to have been discontinued sometime in the early 2000s.
Omaha the Cat Dancer
Outrim, a hard science fiction comic about genetically uplifted rodents operating a scruffy space freighter.
Outside Interference: A newspaper-strip style in a Slice of Life style, without much of an overarching plot.

P-T

The Pride of Life: A webcomic about a dog-like teenager named Kedamono, who, after eating a legendary fruit, transforms into a 'superbeast' and gains super powers. He quickly finds out that this isn't necessarily a good thing. Largely a comedy with fantasy elements.

Rocky: A Swedish autobiographical underground comic by Martin Kellerman.
Sandusky
Spooo Presents: An erotic anthology mostly based around gay stories. The two biggest ongoing comics featured in the title are "Coyote River", an Affectionate Parody of sorts to Brokeback Mountain (though it still deals with the same serious issues that the movie did), and "Rocketship Rodents", an Affectionate Parody of Buck Rodgers with its own spin-off, a parody of (of all things) Doctor Who.
- The Author's notes indicate that the similarity between Coyote River and Brokeback Mountain is pure coincidence, as he wasn't aware of it until people compared the first issue to the movie. Also, he seems not to have seen the movie until some time after the release of the second issue.
Super Dinosaur: More of a 'Scaly Comic' really. Stars SD an intelligent T-Rex who wears a robotic battle harness. Aimed at kids, but readers of older ages like it too.
Tom Poes: Highly regarded Dutch comic strip that ran from 1941 to 1986.

U-Z

Valleydog: A comic about a young, mundane coyote who is unwillingly brought into an eccentric town.
