Celebrate Adopt A Cat Month with Sylvester!

Every cat deserves a loving home - and every cat caregiver deserves peace of mind.

This June, Sylvester.ai is celebrating Adopt a Cat Month by supporting cat adopters, showcasing adoptable cats, and giving back to the feline community.

How are we celebrating?!

What is Sylvester.ai?

Sylvester is a mobile app that helps you instantly understand how your cat is feeling, even when they don’t show it. Simply upload a photo of your cat, and Sylvester analyzes subtle features like:

🐾 Eye tension
🐾 Ear position
🐾 Whisker position
🐾 Muzzle tension
🐾 Head posture

Because cats are experts at hiding discomfort, even attentive cat parents can miss early signs that something feels “off.”


Sylvester helps you stay more connected to your cat’s comfort and wellbeing, especially during adjustment or stressful periods!

Looking for Your Next Feline Family Member?

Throughout June, we'll be partnering with rescue organizations and shelters to spotlight amazing cats searching for loving homes.

Follow us on social media to meet adoptable cats, learn their stories, and discover rescue organizations doing incredible work in their communities.

You might just meet your new best friend.

We partner with shelters, working with volunteers and shelter cats to continuously build and improve the dataset that trains our computer vision, giving caregivers a tool that no general AI can replicate.


We're proud to support our shelter partners and their mission by spotlighting the cats who make this work possible.
