Client handout: 5 strange facts about parasites

Christopher Lee, DVM, explains Toxoplasma gondii facts: why most indoor cats rarely shed, plus pregnancy-safe litter tips for cat health

The first survey of parasite control on bison ranches shows most herds are dewormed on a schedule, with little testing to see whether they need it. Researchers say the habit could make resistance harder to manage.

In a session at the 2026 Fetch National Harbor Veterinary Conference, Nathanael Oster, VMD, MBA, walked attendees through the biology, diagnosis, and treatment of the flea tapeworm in dogs and cats, including why cats are affected more often than dogs.

Christopher Lee, DVM, MPH, DACVPM, DACVM (Parasitology), discusses the clinical significance of Toxoplasma gondii, when veterinary professionals should consider testing, and how to communicate the risks of exposure to clients.
