Finally putting this part of my world to text after holding off for so long trying to think it through. I’m very much looking for feedback on this whole idea and progression in my world. Please let me know what you think!

I should also mention that this is in no way in reference to or inspired by any human events or atrocities. That was not my intention, I did not go out and try to find for human tragedies that I could use for my own writing, and this is entirely a figment of my imagination, inspired mostly by other fiction and not real events.

Context for this world is that it is inhabited by intelligent animals, think Zootopia but more sci-fi, and with quite a bit more political and societal turmoil during the time period this post focuses on. Also, these are normal, animal shaped animals, not anthros. They do have human scale lifespans though, if only because a 15-20 year lifespan for a cat is not conducive to detailed character development.

I really need to start with some background information beforehand, otherwise the story feels incomplete.

A pervasive and central part of this world is the problem of predator and prey. But being intelligent animals with their own hopes and stories, it becomes very morally problematic very quickly to hunt and eat your prey, at least for some predators. This brings us to the Feline empire. Some cats came to really enjoy the screams and pleads of their prey and really put effort into making them suffer while eating them, in that way your cat at home plays with its prey and bats it around, letting it go and catching it again till it gives out. Other cats, the vast majority in fact, did not like hunting and eating other animals, but either had no accessible alternatives or the alternatives were prohibitively expensive, it’s extremely hard to convert an obligate carnivore to eating plants, at least physiologically. Still others were completely opposed to eating prey and saw eating prey as eating their comrades and made every possible effort to avoid it.

But as you may imagine, the meat-free alternatives for obligate carnivores were quite limited. Omnivores like most canids had enjoyed something called a Dietary Enzyme Supplement for quite a while now, which is a pill that is taken either with every meal or at regular intervals, that arms the digestive system with artificial digestive enzymes, that can more efficiently break down plant matter, including cellulose, and use those breakdown products to synthesize nutrients in vivo. Nutritional supplements and synthetic meat substitutes had existed for even longer, but they were mainly compatible with omnivores, not carnivores. So Felines that wanted to stop eating prey and stay healthy were forced to mix and match various expensive enzyme supplements for omnivores (they were hard to get in Feline territory) with expensive “special” nutritional supplements, pay close attention to what plant based foods they’re eating to get enough base nutrients like protein, and monitor very closely for the earliest symptoms of malnutrition. And if they were nursing kittens, they would be producing much less milk and less concentrated milk, leading to malnutrition in their kittens. Not to mention even weaned kittens are voracious little things and would be very expensive to feed without prey.

Collectively among the general public, issues with eating prey were weighing on their conscience, and there was a dream of a dietary enzyme supplement for obligate carnivores. A cheap and convenient thing for Felines to essentially go vegan. But their government was Trophist (pro-predation) and gave no funding to these silly ideas of cats not eating meat, and other carnivore groups didn’t seem to care.

That was, until there was. Biochemist Nikita Almondtail and quantum chemist Yvonne Dandelionpaw (note that these are Reddit links while I’m editing those character profiles for posting on Lemmy) had developed ATDP, the first ever nutritionally complete dietary enzyme supplement for obligate carnivores. A pill that only had to be taken once a week, and which will not only allow Felines to digest and more importantly derive all their nutrients from plant based food, but to digest cellulose, and a range a food wide enough to include the softer raw plants. And critically, initial tests on Felines showed that it was safe for use when pregnant, and when nursing, could satisfy kittens’ nutritional demands if done right, and could allow mother cats to produce just as much and just as high quality milk as pure meat eating cats. But, plant based food was more stable and reliable, higher output, and in a time when food insecurity and hunger was rampant among Felines just as it had been the nature of being a hunter, they could have a safe and reliable source of food that they controlled, no cat should go hungry again, all while making peace and even making friends with prey animals! Two cats developed ATDP no less, and it was tailored specifically for Felines! It used brand new technologies that the Felines had recently pioneered, including a newly discovered super-element called Intium. It was a triumph of Feline technology and science, and was poised to rid Felines of the need to kill and eat prey forever. That was, until the king of the Feline empire personally banned its production or further development, first stating that it unpatriotic and “against nature”, though changed his narrative to saying that it wasn’t safe for Feline to use after strong public pushback.

This triggered a series of events that would lead to the outbreak of the Feline revolution, quickly escalating into the Feline civil war. Unitist (essentially, vegan socialist) movements among Felines had been growing steadily for a long time, and this is not the first time Unitists engaged in civil disobediece and even attempted insurgency, but the banning of ATDP pushed the Feline population over the edge and support for a Unitist revolution skyrocketed. The public had had it with their Empire and was determined to dismantle it in favour of a Unitist republic, just like the Unified Territories next doors. The empire responded with violence and terror against these Unitist cells, determined to silence them. This was when Yvonne Dandelionpaw and Nikita Amondtail came back together, using the knowledge they learned from developing ATDP, namely protein science and Intium, to develop a weapon to turn the tides in favour of the Unitist revolutionaries.

They came up with something they called Catsbane, a neurotoxin developed by the Feline Unity Army and was used to assassinate numerous key figures of the Feline Empire they were trying to overthrow. Basically, they would find a way to tamper with the supply chain of mouse and bird meat, lacing the meals of the royal elite with the poison in highly targeted assassinations. There were even cases of captured prey animals slated to be eaten by high profile individuals who willingly took the poison in order to pass it on to the cats, with the long delay to symptom onset allowed them to not experience the effects until, you know. Being a pro-drug, the chemical would be absorbed through the intestines and slowly processed by the liver into its physiologically active, toxic form. It would then travel into the brain where it interferes with the surface proteins of neurons such as ion pumps and neurotransmitter receptors.

It was engineered to kill as silently and non-dramatically as possible. Victims would not feel symptoms for anywhere between days to over a week, at which point they will experience insomnia, disorientation and disassociation, memory loss, escalating into unresponsiveness and coma, before death comes about two to three weeks later. The “Catsbane stare” was coined to describe the blank expression late stage sufferers would develop as their brain shut down. The chemical is very difficult to detect before symptoms set in, and there is no antidote. Catsbane was also nicknamed “peaceful rabies”, due to the fact that it has a period of no symptoms post exposure, is hard to detect until it’s too late, and it targets the brain.

A total of 120 assassinations were carried out with Catsbane, all in the Feline Empire’s military or royalty, and it was a major contributor to the success of the revolution, with most agreeing that cats would be still eating prey if it wasn’t invented. Obviously, this was extremely controversial. Many supporters of the revolution argued that this poison was much more merciful than the cats who ate prey gave their victims (getting eaten would also be up there in horrible ways to die, but that’s not a medical condition), while many others questioned the integrity of a movement by cats who claim to want to live in harmony with their former prey animals engaged in killing other cats.

After the revolution, the new Feline Democratic Republic, the Unitist republic, banned the poison as a Schedule 1 chemical weapon. The state-run Feline Science Institute is usually very open about providing anyone with their research and papers for free, but the synthesis of Catsbane is a notable exception. Some believe not even they have the synthesis procedure anymore and that all documents related to how to manufacture it was destroyed (they definitely still have it, though, in secret). Interestingly, the general Feline public had nearly complete support of these assassinations, but many prey animals (generally prey animals who lived in the nearby Unified Territories which was already Unitist for a long time) criticized it as even Unitist Felines were still killing animals, and highly polarized opinions among prey animals living within Feline territory (called the prey diaspora, long story). Many ended up trusting the Felines enough to stay and the Feline government post revolution is committed to making sure they are safe and can lead good lives alongside Felines.

For Felines themselves (all animals in Feline territory actually), the Feline government is constitutionally required to ensure both plant based food and dietary enzyme supplements will always be freely and readily available to all animals in Feline territory, as that was a massive part of the revolution. The signing and near unilateral support of the Interspecies Peace Agreement banned predation, for all Felines anywhere in the world, from the cheetah to the domestic cat, in theory forever.

There are rumours that the Unified Territories, which included the native territories and governments of their regular prey animals like rodents and birds, as wells as small to medium omnivores like dogs and foxes, aided the Feline Unitist side. But no they definitely did.
