Feline leukemia (FeLV) has long been one of the most misunderstood—and often feared—diagnoses in the cat world. In this eye-opening episode of the Community Cats Podcast, host Stacy LeBaron welcomes feline leukemia advocate and expert Margaret Tompkins to break down the myths, realities, and latest advancements surrounding this complex virus.

Margaret shares her personal journey into the world of FeLV advocacy, sparked by a group of rescue kittens that changed her life. From there, she dives into the science behind feline leukemia, explaining how it differs from FIV, how it spreads, and why today’s understanding of the disease is far more hopeful than it was just a few decades ago.

Listeners will gain clarity on key topics such as progressive vs. regressive infections, the importance of spay/neuter in disease prevention, and whether testing is always necessary—especially in TNR (trap-neuter-return) programs. Margaret also tackles one of the most emotional questions caregivers face: what to do when a cat tests positive, and why euthanasia should not be the default response.

The conversation also explores managing mixed households, vaccine advancements (including promising new mRNA technology), and how strong immune systems play a critical role in outcomes for FeLV-positive cats.

Whether you’re a rescuer, foster, veterinarian, or cat lover, this episode offers practical guidance, science-backed insights, and a much-needed shift in perspective. Feline leukemia is no longer a guaranteed death sentence—and with education, compassion, and proactive care, these cats can live meaningful, happy lives.
