Somewhere in a Museum Hangs Your Cat's 400-Year-Old Twin. This Free App Finds It.

There is a specific joy in discovering that your ordinary house cat is the spitting image of a haughty aristocrat immortalized in oil three centuries ago. That’s the entire promise of Pet Portraits, a feature tucked inside Google’s free Arts & Culture app, and it delivers the promise about as reliably as a slot machine, which is to say the misses are half the fun.

How it works

The setup takes about thirty seconds. Download the Google Arts & Culture app on iOS or Android, open it, and tap the rainbow camera button at the bottom of the screen. Snap a photo of your pet, and a machine-learning model compares their face against tens of thousands of artworks pulled from Google’s partner institutions, then hands you back the closest matches with a percentage next to each.

It isn’t just for dogs and cats, either. The feature will run your bird, fish, reptile, horse, or rabbit through the same treatment, so the goldfish circling your desk can finally learn which serene Chinese watercolor it was born to star in.

Where the matches come from

The reason the results feel legitimate, even when they’re absurd, is that they’re drawn from real collections. Your pet might get paired with an ancient Egyptian figurine, a burst of Mexican street art, or a formal European portrait, with source works coming from heavyweight institutions like the Rijksmuseum in Amsterdam, New York’s Metropolitan Museum of Art, the Phillips Collection in Washington, and the National Portrait Gallery in Australia, among many others. It’s less a filter than a scavenger hunt through art history, with your pet as the clue.

Manage your expectations (that’s the point)

Let’s be honest about the output: you are probably not going to frame it. The matches land somewhere between “uncanny” and “how on earth did it get there,” closer in spirit to those famously botched fresco restorations than to a commissioned portrait. But that gap is exactly what makes it worth doing. You can feed it new photos and refresh the comparisons endlessly, and the sharing feature is built for firing your dog’s Renaissance alter ego into the group chat. It’s also a low-stakes window into how image-matching AI actually “sees,” clocking a curve of the ear or a set of the eyes and reaching for the nearest thing in a vast catalog.

Still going strong

If you tried this a few years back and assumed it had quietly disappeared like so many novelty apps, good news: Pet Portraits is alive and well in 2026, still free, and still folded into the same Arts & Culture app. If anything, the pool of partner artworks it draws from has kept growing, which means your pet’s museum twin may be a different painting than it would have matched a couple of years ago. Point your phone at the cat, take the shot, and see which long-dead masterpiece has been waiting for them the whole time.
