Let me take you back to my middle school days when I thought these books were the shit! I was obsessed with the warrior cat books so bad! These 3 British crazy cat widow ladies made this cat war series in the early 2000s. They were made for kids yeah but honestly it was the darkest and bloodiest books series! It was like reading an intense soap opera, but with cats?? Everyone thought I was reading cute kitten books but really I was reading about cats planning mass murder genocides and fighting in brutal wars.
Here is just some of the horrible events that I remember on the top of my head: cats being mauled and ripped apart by wild dogs, a cats face being torn off and it lived?!, many plagues and sometimes biological warfare, secret forbidden love affairs, cat version of the trail of tears, cats being gutted, cats being severely disabled, cats drowning/falling/crushed/smashed to death which was common, plots of assassination and murder (also common), religion vs atheists, a ton of dreams about drowning in rivers of blood, tons of war, psychopath serial killer ghosts, and more idk basically every chapter someone brutally dies.

In the comic above, after she told the dude they weren't her kids he let the kids go. One of the kids murdered him and threw his body in the lake. She escaped in ghost tunnels but was crushed by a mudslide. I don't know what happened afterwards since I ditched the books but I bet it's more of the same shit. I'm so nostalgic rn!
