Cats of all ages require omega 3 fatty acids for the healthy functioning of their minds and bodies. Omega 3 fatty acids have anti-inflammatory properties that help prevent inflammatory diseases like allergies, organ damage, arthritis and cancer. These essential nutrients also help promote the healthy growth of cat’s coat and muscles.
In a Hurry? Here are Our Top Choices
When cats are unable to obtain the omega 3 fatty acids from their diet, their body becomes malnourished. Cats that are deficient in omega 3 fatty acids usually suffer from joint pains, weak eyesight, heart diseases, kidney failures and poor coat health.
Fish oil is the best source of omega 3 fatty acids. It is extracted from the tissues of oily fish. However, feeding your cat a fish during mealtimes may not necessarily provide it with the right amount of omega 3 fatty acids that it needs.
This is why, veterinarians recommend giving cats fish oil supplements that contain 25-30mg/kg of body weight of EPA and around 40mg/kg of DHA. A cat that weight 10lbs will need 200mg of DHA per day. EPA and DHA are the two specific kinds of omega 3 fatty acids that cats need in their diet.
