Because your cat has a world-class poker face
Cats are brilliant at hiding discomfort - it’s in their nature to suffer in silence, and hide their true feelings even from the people who know them best. That’s why one of the most powerful skills you can have as a cat caregiver is understanding your cat’sunique comfort baseline.
"When you know what is "normal" for your cat today, you can act with confidence the moment something shifts tomorrow."
-Dr. Matt McGlasson.
The Sylvester mobile app makes this observation easy by using US-patented feline science to translate subtle facial cues into objective comfort insights. One photo, objective insights about your cat’s comfort.
