What an AI pet companion can do
Mrrp helps you track symptoms, spot patterns, and prepare for vet visits— all in one calm place.
She was my best friend. My one-third. She deserved a way better human than me. This is her story, and why Mrrp exists.
Working on Mrrp, an AI companion for everyday pet care, memories, and calmer routines with the animals you love.
A jealous, dramatic cat who wanted her hooman to herself and somehow became a one-third soulmate in our little family joke.
Not to relive how I lost her, but to remember her as she really was and to be honest about the attention, time, and presence I sometimes failed to give.
A quiet apology and a promise. A way to help other hoomans notice the small moments with their pets before those moments turn into regrets.
I'm not going to tell you how I lost her.
Not because it's too painful—though it is—but because that's not what Mrrp is about. I didn't build this app to cry. I built it to remember her the way she actually was: stubborn, dramatic, fiercely loyal, and honestly kind of a brat.
Her name was Willow. And she deserved a way better human than me.
My one-third
There's this joke I have with my partner. She knows about it. Willow definitely knew about it too, even if she pretended not to understand human words when it was convenient for her.
The joke goes: I have two soulmates. My girlfriend, and Willow. Which makes each of them my one-third.
"Wait, that math doesn't work—"
Yeah. Willow didn't care about math. She cared about being acknowledged as an equal party in this relationship. Which she was.
Look, I know how it sounds. But if you've ever had a pet who really, truly got you—not just tolerated you, but actually understood your moods and your silences and the specific way you breathe when you're about to cry—then you know exactly what I mean.
The jealous type
Willow had opinions. Strong ones.
At the top of that list: she hated—and I mean hated—every single cat I ever touched. Pet a friend's cat? She knew. She could smell it. And she would spend the next hour giving me the most dramatic cold shoulder you've ever seen from a four-legged creature.
My girlfriend? Also on the list, at least initially. Willow tolerated her eventually. "Tolerated" is doing a lot of heavy lifting in that sentence. There was always this look, like: "Fine. She can stay. But I was here first, and don't you forget it."
I never forgot it. I don't think my girlfriend did either.
What I got wrong
Here's the part that's hard to write.
I wasn't always there. Work got busy. Life got busy. There were too many evenings where I came home late and she'd already given up waiting by the door. Too many weekends where I was "too tired" to take her somewhere new. Too many times I looked at my phone instead of at her.
She never complained. Dogs don't, not really. They just wait. They adjust their expectations down, bit by bit, until whatever scraps of attention you give them feels like enough.
But it wasn't enough. I know that now.
Mrrp is, in some ways, my apology. I can't go back. I can't give her the attention she deserved. But maybe—maybe—I can help someone else not make the same mistakes I did.
That's not a marketing line. That's just the truth.
Why Mrrp is not another AI pet
You've probably seen them. The AI companions. The virtual pets that never die, never get old, never need you to actually get off the couch. They're always there, always happy, always ready to "interact" in whatever sanitized way the algorithm decided is optimal.
That's not what Mrrp is. And honestly? Willow would have hated that.
She was jealous of cats. Cats. Real, breathing, fur-covered creatures. You think she would have tolerated some digital thing getting my attention? Please.
Mrrp's job is not to give you:
The connection you can make with a real cat or dog—the kind that looks at you and actually sees you—can never be achieved by a soulless AI. I don't care how good the language model gets. It's not the same. It will never be the same.
Mrrp exists to help you be more present with the real pet in your life. Not to give you an excuse to avoid getting one, or to replace the one you've lost. If you ever want a more practical breakdown of what an AI pet companion can and cannot do, there's a separate that goes into the features without pretending they're magic.
Why I built this
When Willow was here, I didn't track anything. I didn't log her meals or her weight or the little changes that, looking back, might have meant something. I just... lived with her. And when things went wrong, I was scrambling to remember dates and symptoms and what she ate three weeks ago.
That's not good enough. Your vet deserves better information. Your pet deserves better advocacy. You deserve to not feel like you're failing at the one job that actually matters.
So I built the thing I wish I'd had. A calm place to track health, diet, memories, and the random 2am thoughts you have about your pet. Not to obsess. Not to turn pet ownership into a spreadsheet. Just to help you notice things and remember them when it counts.
And if you're ever in doubt about what's normal or not, this story—and even —is not a substitute for talking to an actual vet. Places like have solid, no-nonsense guides. Use tools like Mrrp to collect the details, then take them to someone who knows your pet's body better than an app ever can.
For you
If you're reading this, you probably have a pet. Or you had one. Or you're thinking about getting one.
Here's what I want you to know: you're going to mess up. You're going to be too busy sometimes. You're going to look at your phone when you should be looking at them. That's okay. That's human.
But also: notice them. Write down the weird thing they did today. Take the photo even when the lighting is bad. Log the vet visit. Because one day you're going to want those memories, and they'll be gone if you don't capture them.
Mrrp can help with that. Not in some magical AI way. Just in a "here's a place to put things so you don't forget" way.
Willow is gone. I can't get her back. But if this app helps even one person be a slightly better pet parent than I was, then maybe building it was worth something.
Questions people ask
Not exactly. Mrrp won't fix losing a pet. What it can do is help you pay closer attention while they're here and keep a clearer record—so you have fewer "I wish I'd noticed sooner" moments later.
No. There's no digital Willow living in my phone, and there won't be one in yours either. Mrrp is a companion app that helps you track health, routines, and memories for a real animal—not a virtual one.
No. If you can write a short note, snap a photo, or tap a reminder, you can use Mrrp. It's built for real life—busy days, messy routines, and the kind of love that doesn't always look perfect from the outside.
