He eats Chicken Soup kitten, which is incidently rated higher than like 95% of all the ferret diets out there...and much cheaper too! I've been told by some ferret folks on a ferret forum that I should just give him a live mouse to kill and eat, but eh...my snake does just fine with frozen thawed mice, I don't see why the darn ferret is being so picky when the dogs and the snake aren't. :lol: Then again, ferrets have all the same problem that dogs and cats do with commericial diets. Back when they were first domesticated like 2500 years ago or whatever to hunt rabbits and whatnot, I'm sure they didn't get to eat a commercial diet either.
But as far as the parasites go, I don't check for them except during their once a year fecal. One of my fosters about a month ago had tapeworms, ick...had to make sure to pick up after him very well! Even though our mice in our research lab are cleaner than the average pet store mouse, I still freeze the mice for at least a week or two to kill the parasites, though occasionally if I'm in a pinch, she (the snake) gets a freshly killed mouse.
