Hi all, I have some friends who are currently doing their vet. internships. They recently attended a seminar on exotic animals where the person instructed them that ferrets should never be fed cat or kitten food. They were told that ferrets can develop crystals in their urinary tract from it just as cats can. I have been mixing Iams kitten food in my ferrets food and now I'm not sure I should continue. I wondered what the rest of the ferret community thinks of this. Has anyone had a problem with their ferrets developing crystals in their urine because they were feeding kitten food?
