Does anyone know specifics about whether my WC Russian tort could have been infected with coccidia when she was imported to the USA a year ago? She's been healthy, eating like a pig (thus, Miss Piggy) and active up until the beginning of May. Has a large load per vet and has started treatment with Albon. Do Coccidia lay dormant until conditions are right, then start their life cycle in the host animal. Once treated and cured, can the host animal gain immunity?
