No, feeding sardines a couple times a week would not be adequate calcium except for those sardines. Each meal needs to have the amount of calcium that it needs and the calcium in sardines is only enough for sardines. Look into See Spot Live Longer Dinner Mix or Dr Harvey’s Veg to Bowl Fine Ground. They are premixes with all the vitamins and minerals in them for boneless meat. Depending on what else you feed, you may have to add oil too, but other than that they are easy and complete.
