Just my two cents. Keep in mind you may be defeating the purpose of feeding block by adding high sugar content (sweetened cranberries) that causes calcium loss out the urine. Same with adding equal amounts of block and avocado, which is very high in phosphorus to calcium ratio, and has a high fat content, as this source can tip the Ca:P negatively. Instead adding in fresh fruits, and a bit of organic Chia oil "Foods Alive", for a little of this oil has been found to go a long ways to adding to 'taste appeal' without adding a significant amount of fat and phosphorus to the diet.
