For cats and dogs, on macOS
Your pet. In 3D.
On your Mac.
Download the app, add a few photos, see them in 3D in about five minutes. Then your own cat or dog lives on your Mac: walking the Dock, napping on your windows, looking up when you move the cursor.
Free to try. See your pet in 3D before you pay anything.
This is Milo, a border collie made from three photos. Drag to turn him, tap a behaviour to see it.
How it works
From a photo on your phone to a pet on your Dock

1
Add a few photos
Download the app and add a side view and a face. We check each one and tell you exactly what would help.

2
See them in 3D
In about five minutes, right in the app. Turn them around, compare with your photo, and ask for changes. Free.

They live on your Mac
Keep them for one payment and they hop out of the Dock. Then they make their own plans.
Alive, not looping
They decide what to do next
No GIF on repeat. Your pet wanders, rests and reacts on their own schedule, and stays out of your way.

Walks the Dock
Pads along the top of your Dock, stops to sniff an icon, carries on.

Naps on your windows
Finds a quiet window edge and curls up. Slow breathing, twitching ears.

Follows your cursor
Turns their head to watch it, and sometimes gets up to follow.

Loves being petted
Hover to pet. They lean in and close their eyes.

Stretches and grooms
A long play-bow stretch after a nap. A thorough wash after that.

Settles down
Lies down when you've been typing a while, and keeps you company.
Not a sprite
Your pet, not a pet
Desktop pets have always been pixel art: a generic cat, maybe tinted the right colour. We rebuild yours in 3D from your photos, so the white sock, the one floppy ear and the way they sit are all theirs.
And because it's real 3D, they can turn their head to look at you.

In memory
For the ones who aren't here anymore
Some of the pets we make have passed away. Tell us, and we'll take extra care: gentler words, no comic moments, and a person checks every detail before you see them.
Memorial petsGifts
Give someone their pet
They add the photos, you cover the rest. Gift codes are coming soon; in the meantime, a share link to your own pet makes a lovely surprise.
Pricing
Free to see. $19 to keep.
One payment, no subscription. Your pet on up to 3 Macs, two free regenerations, and every behaviour we add later.
See pricingOur promise
If it doesn't look like your pet, you get your money back.
14 days, no questions. And you see them in 3D before you pay at all.
Which Macs does it run on?
Apple silicon Macs (M1 or later) on macOS 14 Sonoma or newer. One purchase covers up to 3 of your Macs.
Will it drain my battery?
It's built to be lighter than a browser tab. Your pet sleeps when you're away, slows down on battery, and never blocks a click or steals focus.
What happens to my photos?
They're used only to make your pet. We delete them 30 days after delivery, or straight away if you ask, and we never train on them unless you opt in.
What if it doesn't look like my pet?
You see your pet in 3D before you pay. If something's off, tell us what and we'll try again: two regenerations are included. And if it still isn't your pet, you get your money back.
Is it a subscription?
No. You pay once for your pet, and every new behaviour we add later is included.
Does it work on Windows?
Not yet. staywith.pet is Mac only for now, so we can make it feel at home there first.
Who's coming to live on your Mac?
