Looks like this product isn't that good for small animals anyway.
Ingredients: Sweet Potato Flour, Rice Flour, Salt and Annatto

Product Review: Brown's Tropical Carnival Sweet Potato Baked Crisp Chips
There are two ingredients we have concerns about here. First, there's rice flour. Guinea Lynx warns that rice flour should be avoided in pellets because it's a byproduct with no nutrient value.
Second, there is annatto, which Wikipedia says "is derived from the seeds of the achiote trees of tropical and subtropical regions around the world. The seeds are sourced to produce a carotenoid-based yellow to orange food coloring and flavor." Guinea Links also warns that seeds should be avoided because they're too high in fat and protein, and that food coloring should also be avoided.
Much as it pains us to turn down a treat, we're going to have to err on the side of caution and insist that our humans not tempt us with this treat due to these questionable ingredients. We'll have to give Brown's Tropical Carnival Sweet Potato Baked Crisp Chips 1 out of 5 stars
