Benefits of Fish in a Cat’s Diet

Omega-3 Fatty Acids

The inclusion of fish in a cat’s diet can offer a boost of omega-3 fatty acids, promoting heart health and reducing inflammation. This is especially beneficial for cats with joint issues.

Protein Source

Fish serves as an excellent source of high-quality protein, aiding in muscle development and maintenance. It complements other protein sources in a cat’s diet.

Improvement in Coat and Skin Health

The natural oils in fish contribute to a lustrous coat and healthy skin, adding an aesthetic advantage to including fish in a cat’s culinary repertoire.
