Your Vet Recommended sylvester.ai.
Here’s Why.

Cats are masters at hiding pain. That’s why your veterinarian may have recommended sylvester.ai—a tool that helps detect signs of discomfort using just a photo of your cat’s face.

Whether your cat isn’t acting like themselves or you’re simply keeping an eye on their health, Sylvester gives you an easy way to stay proactive—right from home.

What is sylvester.ai?

Sylvester.ai is a web-based tool that uses artificial intelligence to assess whether your cat may be showing signs of pain. It’s built using thousands of expert-reviewed images and validated facial pain cues.

  • One free assessment per household

  • Fast, easy, and built specifically for cats

  • Monitor assessment history over time within sylvester.ai

Think of it as a digital check-in—use it when you’re concerned and as part of a regular care routine.

Why Did My Vet Recommend syvester.ai?

Your vet knows that the signs of pain in cats can be subtle or easy to miss—especially at home.

Sylvester helps you:

  • Check in regularly on your cat’s comfort and wellbeing

  • Track patterns over time that may be hard to notice day to day

  • Support your vet’s care plan with better insights between visits

Even if your cat seems okay, ongoing monitoring helps catch changes earlier—when it’s easier to act.

A Few Things to Know:
