Basically ok
These are large cuboid cat biscuits, each one several times the overall size of typical food. Beyond this, there doesn't appear to be anything special about the food or the effect. It seems perfectly popular in terms of taste and I have nothing negative to say about this product.
However, I'm not sure I have anything positive either. We have found using enzymatic toothpaste and attempting to brush once+ a week produces seemingly more effective results.
