By Sylvester.ai
Sylvester.ai is changing cat care globally. Since cats instinctively hide discomfort; Sylvester.ai helps caregivers actively monitor their cat at home for subtle changes in health while also increasing revenue for veterinary professionals in between vet visits.
With a single photo, Sylvester.ai analyses facial cues linked to discomfort, giving pet owners reassurance and veterinarians a quicker way to assess patients. Beyond one scan, Sylvester.ai creates a history of results that can be shared with clinics and used to guide treatment decisions.
By combining AI with validated veterinary science, Sylvester.ai makes feline health monitoring available at home and in practice. Sylvester.ai is not just delivering technology. It is changing how the world understands cats, making care more proactive, more collaborative, and more compassionate.
The best thing to happen in veterinary medicine.

Offering Sylvester is a meaningful value-add that keeps caregivers connected to their cat's health between visits and better informed when they arrive at appointments. When your clinic introduces Sylvester to a caregiver, that relationship is anchored to you. Caregivers connect through your unique clinic link, their Cat Comfort Check results flow to your Practice Portal, and every follow-up conversation comes back to your team.
It is also a ready-made marketing tool. Use it in your social posts, client newsletters, wellness plans, or as a giveaway to engage your community. We provide partner marketing assets to make that easy, including social content, blog posts, and a partner badge for your website.
The result is more vet visits, stronger caregiver engagement, deeper clinic loyalty, and better outcomes for feline patients.
Caregivers take a photo of their cat at home and receive a clear comfort result in seconds. Over time, Sylvester builds a history of results that caregivers can share directly with your team, giving you visibility into how a patient has been feeling between appointments. Your clinic accesses everything through a simple Practice Portal.
Sylvester is trusted by 12,000 active caregivers and partner clinics worldwide, guided by PhD animal behaviourist Frances Valentine and grounded in validated veterinary pain science.
Sylvester.ai was founded by animal health entrepreneur Susan Groeneveld, whose career has spanned multiple animal health companies and whose personal experience revealed the urgent need for better tools to detect pain in cats. After losing her farm cat Jack, who silently suffered without anyone realising the extent of his discomfort, she set out to change how the world understands feline health.
The belief behind Sylvester.ai is simple: cats deserve better care, and caregivers and veterinarians deserve better ways to provide it. Using advanced artificial intelligence combined with validated veterinary pain models, Sylvester.ai turns a single photo into a clear and consistent assessment of a cat’s comfort.
Sylvester.ai is guided by the mission to bring relief to the millions of cats suffering in silence, while enriching the lives of both cats and their caregivers. The vision is that all cats should have access to ongoing health assessment, whether at home, in the clinic, or through integrated partner platforms. Grounded in values of compassion, transparency, and science, Sylvester.ai is shaping a future where feline pain no longer goes unnoticed. Find out more details about sylvester.ai here.
