I know of a lot of furry shit, but most of it isn't good.
Freefall, Faux Pas, Poppy, Prequel, Lackadaisy, Jasper Gold, and Endtown all have already been mentioned in this thread.
VGCats used to be OK until Scott got himself a kid, now it updates 1-4 times a year.
Sequential Art used to be halfway decent, but somewhere along the line Jollyjack lost it and hasn't been able to make a funny strip since. His artwork will never improve either.
At least those two are halfway alright. Now for some crap.
Jack. Extreme 90's style edge with Tiny Toons artwork. I personally enjoy the edge a great deal, but if that's not your thing than all the murder and rape will be a turn off. Was on hiatus last I checked due to drama.
Kevin and Kell. Generic newspaper strip, furry style. It's actually worse than it sounds. It tries so hard to make jokes, but fails horribly 99.99999% of the time. Almost like the writer understands what a joke is, but has no idea how to make one. Actually ended and then came back from the dead a while back.
Ozy and Millie. Calvin and Hobbes wannabe with an author who can't stop inserting personal fetish material and personal political rants. Was pretty popular, finished, author has since cut off dick and now does newspaper comic about little girl and unicorn, now with 200% more smug self-superiority.
S.S.D.D. Terrible fucking artwork, that improves in a minor way over the series. The plot is always crap, and almost goes out of it's way to remind you the author is British as often as it can. It's pretty much shit, without being 100% shit.
Carry On. Followed the link from Freefall. Starts of with standard mid90's-early2000's furry plot and theme stuff(cons, cosplay, etc), then goes into a plot involving some African country, and has been in that plot arc for years on end now. Actually better now with the plot than it was before, but it's still not that good.
I can name much more.
