About The Lils

Homemade cat food, formulated by two former professors and approved by one very opinionated cat.

OUR STORY

It started with Pishi

The Lils started with a small black cat from a shelter. His name is Pishi, and from the first day he made it clear that he had standards.

He also came with a stubborn health issue that vet visits and a long list of commercial foods never quite solved. We cook real food for ourselves, so we asked the obvious question: why not for him?

The question turned out to be harder than it sounds. Cats need more than meat. They need dozens of nutrients, each in the right amount, and some in the right ratio to each other. So we did what we were trained to do: we went to the research and built his meals one recipe at a time. Slowly, we watched him become a healthier, happier kitten.

Every cat deserves that. That is why The Lils exists.

THE PEOPLE

Who we are

The Lils is a family business run by two former professors. We left academia to do this full time.

Shahab’s field is operations research, the mathematics of making the best decision under constraints. Sadie’s is business analytics and healthcare decision-making. One of us formulates the recipes. The other makes the videos, runs the social channels, and answers your emails. We started The Lils to make healthy food available to every cat, at a price every owner can afford.

We are not a pet food company. We are two people who went all in for our cat, then kept going for everyone else’s. Everything on this site, from the recipes to the code, was built by the two of us.

THE METHOD

How we formulate

We treat every recipe as an optimization problem. That is the day job talking, and it is also the only approach we trust. The inputs are what the scientific literature says a cat needs. The output is a recipe that meets those needs with ingredients from a regular grocery store.

Each recipe is formulated against the three standards the pet food industry itself uses: FEDIAF (the European Pet Food Industry Federation), AAFCO (the Association of American Feed Control Officials), and the NRC (the National Research Council). We model every nutrient in every ingredient, then adjust until the numbers check out at every batch size you might cook.

We also model our recipes on a prey-style diet, so the balance of muscle meat, organs, and nutrients stays as close as possible to what a cat would eat in nature. Mealtime should feel natural to your cat, not engineered.

Real ingredients are not uniform. The fat in a chicken thigh, the vitamin A in liver, the taurine in heart all vary from one package to the next, and most recipes use a single average number for each. Ours do not. We build that natural variation into the model, so a recipe meets the standards across the range you will actually bring home, not only on an average day. It is the most demanding part of the work, and the part most recipes skip.

TRANSPARENCY

We show our work

The full nutritional analysis of every recipe is published openly, before you buy, so you can see exactly what goes in the bowl. Every supplement is listed with its exact dose and where to buy it. Every recipe comes with an instructional video and step-by-step photos. The guesswork is our job, not yours.

Take the analysis to your vet. We mean that. A recipe formulated this carefully should welcome a second pair of eyes, and your vet knows your cat.

AT OUR HOUSE

Our cats eat this every day

Our own cats, Pishi and Lili, have been raised on these recipes since we adopted them as kittens. Their regular vet checkups and bloodwork have been consistently normal.

That is our story, not a promise. No food is magic, and we will never tell you otherwise. What we can say is that we feed our family exactly what we sell, and we would encourage the same for yours.

THE FAMILY

Meet the team

Shahab Derhami, co-founder of The Lils

Shahab (Sean) Derhami

Co-founder, Formulator and Chef, Pishi’s dad

Shahab turns the science of feline nutrition into recipes a home cook can follow. He built The Lils formulation method, which treats every recipe as an optimization problem and checks it against the industry’s nutrition standards at every batch size, and he cooks each recipe on camera so you can see every step. He came to this with a PhD in industrial and systems engineering from Auburn University and about a decade of optimization work at Georgia Tech and Binghamton University, where he was a professor of business analytics and operations.

“I want every cat to eat a healthy meal, and every cat owner to be able to afford one. Our job is to make that as easy as we possibly can.”

Pishi has reviewed this plan and has no objections, provided breakfast is on time.

Sadie Mir, co-founder of The Lils

Co-founder, Content and Customer Care, Pishi’s mom

Sadie creates the videos, runs our social channels, and answers when you write to us. She wants you to understand what goes into your cat’s bowl and feel comfortable asking questions along the way.

Before co-founding The Lils, Sadie built a career in healthcare analytics and teaching. She earned her PhD in operations management and business analytics from the University of Alabama, researching medical decision-making for patients with chronic disease. Most recently, she was a professor of business analytics and operations at Binghamton University, where she was recognized by Poets & Quants as one of the top 50 undergraduate business school professors of 2021.

That background shapes her approach at The Lils: ask careful questions, look closely at the evidence, and make complex information easier to use.

“I’m someone who asks a lot of questions, especially when it comes to Pishi. At The Lils, I want to help other cat parents understand the thinking behind what we do, not just follow the steps. And if something doesn’t make sense, I want them to feel comfortable asking.”

She is also Pishi’s self-appointed number one fan. The title is not up for debate.

Pishi, a black cat and Chief Quality Officer at The Lils

Pishi

Chief Quality Officer

Pishi graduated Suma Paw Laude from the prestigious Purrinton Institute of Tastology, with a dual degree in Advanced Napping and Recreational Knocking Things Off Tables. He joined The Lils immediately after as Chief Quality Officer. Every recipe passes his inspection before it goes on the site, an inspection he conducts by eating it. Since then, not a single bowl has been left unfinished, not a single recipe has been turned down, and not a single nap has been skipped. He now also supervises one intern.

Lili, Taste Tester Intern at The Lils

Lili

Taste Tester Intern, Reports to the Chief Quality Officer

Lili, formally Miss Lillian, joined The Lils without a degree from the Purrinton Institute of Tastology, but with considerable confidence in her qualifications. She was not the cat we went to the shelter to meet. From the cage next door, she meowed, pawed, and insisted on an interview. She was hired on the spot.

She approaches taste testing with enthusiasm, sampling her own food and then checking the toppings on her boss’s. Her other specialties include fetch, standing on two paws, and expressing opinions at a volume that requires no follow-up. She reports to the Chief Quality Officer, although she regularly takes his seat on the cat tree. She considers this career advancement.
