How CatDX.com started?
Our pledge
In 2018, our founder's cat was suspected of having FeLV. The vet visit cost $180 and was stressful for everyone. We built CatDX so cat owners have a gentler, more affordable option — saliva testing that matches the accuracy of in-office vet tests, trusted by adoption centers across the USA.
Our mission: to create a friendlier, stress-free, and affordable alternative for cat owners. This is why we started CatDX.com
Our Science: The CatDX Difference
