Whipworms in a cat?
A fecal sample was submitted from an adult female cat in Oklahoma as part of a routine annual wellness examination. This organism was found on fecal float. What parasite is this?
The feline whipworm, Trichuris felis, referred to by some authors as Trichuris campanula, is considered rare in cats in the continental United States other than occasional cases reported from southern Florida. Further discussions with the owner of this cat revealed she had recently moved with her cat to Oklahoma from the Caribbean. Looks like the cat and owner weren’t the only animals that moved! Although nothing is labeled to treat this parasite in cats in the US, something labeled as effective for whipworms in dogs, such as fenbendazole, milbemycin, or topical moxidectin would be expected to be effective.
