Cats are experts at hiding discomfort. Sylvester gives you a way to check in. Using a simple photo of your cat's face, get comfort insight in seconds built on validated feline pain science.
Why cat caregivers use Sylvester:
→ One photo, instant comfort insight
→ Built on validated pain scales used in clinical and research settings worldwide
→ Track comfort over time and notice changes sooner
→ Share results with your veterinarian for more informed conversations
→ Over 20,000 cats on the platform
How it works:
1. Take a clear, front-facing photo of your cat's face
2. Receive a comfort insight within seconds
3. Follow your cat's comfort history over time
Important:
Sylvester is a support tool, not a diagnosis. If you're concerned about your cat's health, please contact a veterinarian. Photo quality matters — good lighting and a fully visible face give the best results. Some breeds or life stages (such as kittens) may not be supported.
