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. This is why we started CatDX.com
