I have to second chesca on the oxbow simple rewards, they're super high quality and healthy treats! I feed these on occasion and my hams absolutely loved them
Whether you get the mealworms treats or not is up to you. They're definitely healthier than some of the treats on the market, but like chesca said, they have only 1% mealworms in them. If you really wish to offer them, I'd only do so on occasion and remember that they don't replace real mealworms
