Who are we?
Our pledge
Our mission
In 2018, our founder's cat was suspected of having FeLV. The vet visit cost $180 and was stressful for everyone. Dr. A. built CatDX so cat caregivers have an easier, more affordable option—saliva testing that rivals the accuracy of in-office vet tests and is trusted by adoption centers across the USA.
Create a friendlier, stress-free, and affordable alternative for cat lovers.
Our Science:
Saliva is a stress-free alternative to blood draws. CatDX.com is a PCR-based at-home test for FeLV and FPV that matches the performance of leading vet tests.
