Not really.They don't prevent or cure wet tail,and are honestly pointless
Steps can be taken to prevent wet tail,however.These would be avoiding stress as much as possible for your hamster,and using a high quality probiotic(no artificial colors,no artificial flavors,no digest/derivatives/other unspecified biproducts,no maltodextrin/dextrose/sorbitol/or other artificial sweeteners and processed sugars,etc).
