The only torts I ever had dewormed were two imported Russians years ago. Have never been overly concerned about parasites in any of my other long term torts as all seem healthy and robust. My question deals with diet. Is there any natural food that is a natural dewormer or that would keep a minor parasite load from becoming an issue? I believe proper husbandry is probably the best preventative measure in relation to parasites and their effect...but is there is a food that has natural prophylactic properties in regards to parasites?
