Our journey to better cat care
Why CatDX?

In 2018, Kitty was unwell. During a stressful vet visit, he was suspected of having Feline Leukemia Virus (FeLV). The vet recommended a costly and traumatic FeLV blood test, and we knew there had to be a better way (Total visit cost of $180).
Our mission: to create friendlier, stress-free, and affordable alternative for cat owners. â This is why we started CatDX.com

â â â â â "Responsive customer service, good packaging, easy test to administer swab. All around good service...." J.

â â â â â "...Vets all over California no longer do virus tests w/out a full and complete exam. This means that not only is your PCR testing less expensive but when added to the cost of a complete exam your service is important to the rescue community. Thank you" A.N.
