This started as a webcomic, but now it is getting released in print format through Action Lab Comics. I've received the first one and have ordered volume 2 and 3. It's a really fun tale about a cute monster. I highly recommend this if you have young kids that you want to get into comics and reading.
I have not. I only first heard of her about two years when I visited a small local show. Gronk is a fun title for kids and that's what I've read of hers (as I'm not into My Little Pony). I'll have to look up the cat stuff.
