The aim of this study was to optimize the use of bone waste from tuna canneries. So, bone waste from yellowfin tuna was used to produce dietary supplement tablets for cats. The supplement tablets were made from a combination of 2.5 g bone meal and consumed by two groups of domestic cats. Each group consisted of 3 kittens and the number of feedings was two meals per day including group 1: 1 tablet per meal; group 2: 2 tablets per meal. At the end of the period (21 days), the blood samples of the treated cats were analysed for their calcium, magnesium, and phosphorus contents. The results showed a significant increase in the level of calcium in the blood of the cats. Based on the results obtained in this study and the large amount of waste from fish canneries, it is suggested that bone powder be used to improve the mineral content in the blood of cats.
