It's been forever since I've checked up on it, but Peter & Company is one of my favorite webcomics. Wouldn't recommend if you don't like anthro animals, though.

Pretty much the story is about a highschool age cat who gets this imaginary friend like guardian angel who only him and anyone else with a guardian angel can see and hear. There are, from what I remember, some more serious comics, but it, from what I remember, is pretty lighthearted.

Just checked their official website to get the link and they've been slowly continuing the series. Latest update was March this year, so I don't think it's quite dead yet.

There's also a sequel series ( Peter & Whitney ) that I have no idea about since I haven't read much of it that follows the main character of the original and has him as an adult.

Edit:

The second comic tells you he's twelve year old by the time the story starts, so my comment about him being highschool age isn't necessarily correct...

So I post devils panties m-f while im unemployed (I know once im working it will fall off so going to stop it so I can let folks know at that time.). Its not exactly wholesome but its this sorta comic blog so it has things from the artists life and then also little vignettes mostly on how the artist feels about stuff that impacts their life. So like half of it is political stuff now (which I get given the circumstances of the country).
