Re: Rodent Coats and Oils
Unless you are feeding a substandard (non-complete) food exclusively then I cannot see any value to it. Sure oil could help a dry coat (just like in a dog) but if you are feeding a well balanced diet they should be getting all the oils and vitamins they need without supplimentation being necessary.
Keep in mind excess oil means excess fat which will lead to a higher incident of cancer in the long run.
Re: Rodent Coats and Oils
If the animal has a bad coat, it can mean underlying health problems. If your just taking precautions, it may not be necessary with a proper, well rounded diet.
