Comfort insights built on the same science veterinary professionals use.

Sylvester uses computer vision and recognized feline pain science to help you understand how your cat is feeling, right from your phone.

Cats are wired to hide pain. Unlike dogs, they rarely vocalize or limp when something is wrong. Instead, discomfort often shows up as subtle shifts in facial expression such as a slight tension around the muzzle, ears that sit a little lower, eyes that aren't quite as open as usual.

These signs are easy to miss, even for experienced cat caregivers. And because cats tend to mask how they feel, many are living with discomfort that goes unnoticed.
