Zesty Paws Salmon Omega Oil + Hemp is a liquid supplement designed for both dogs and cats, made from Wild Alaskan Salmon oil combined with Hemp Seed oil. This blend provides important omega-3 fatty acids (EPA and DHA) along with stearidonic acid from hemp, which can support your pet’s skin health, immune system, and heart function. The use of wild-caught salmon suggests a good source of quality fish oil, and the liquid form with a pump makes it easy to measure and mix into your pet’s food.

The salmon and hemp flavors are generally palatable for many pets, but some may need time to adjust to the taste. The dosage is straightforward—start with half a teaspoon per 20 pounds of body weight and gradually increase, but don’t exceed 10 teaspoons per day. A single 32-ounce bottle offers a large supply, which is convenient for long-term use. While this product is suitable for all breeds and promotes normal skin moisture and cardiovascular health, it’s important to monitor your pet’s reaction to the hemp ingredient if they are sensitive.

Zesty Paws delivers a trusted option for boosting omega-3 intake and supporting overall wellness in cats and dogs. If your pet prefers capsules or has a particular sensitivity, alternative forms or flavors might be worth considering.

Buying Guide for the Best Fish Oils For Cats

Choosing the right fish oil for your cat can significantly improve their overall health, including their skin, coat, and joint health. Fish oils are rich in omega-3 fatty acids, which are essential for your cat's well-being. When selecting a fish oil, it's important to consider several key specifications to ensure you are getting a high-quality product that meets your cat's specific needs.
Omega-3 Fatty AcidsOmega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), are crucial for your cat's health. They help reduce inflammation, support brain function, and improve skin and coat health. When choosing a fish oil, look for products with high levels of EPA and DHA. For general health maintenance, a moderate level of these fatty acids is sufficient. However, if your cat has specific health issues like arthritis or skin problems, you might want to opt for a product with higher concentrations.
Purity and QualityPurity and quality are essential when selecting fish oil for your cat. Contaminants like heavy metals and toxins can be harmful. Look for fish oils that are molecularly distilled or have been tested for purity by third-party organizations. High-quality fish oils will often have certifications or seals of approval. If your cat has a sensitive stomach or you are concerned about potential contaminants, prioritize products with these certifications.
Source of Fish OilThe source of the fish oil can affect its quality and sustainability. Common sources include salmon, sardines, and anchovies. Wild-caught fish are generally considered to be of higher quality compared to farmed fish. Additionally, sustainably sourced fish oils are better for the environment. If you are environmentally conscious or want the best quality for your cat, look for products that specify wild-caught and sustainably sourced fish.
Form of Fish OilFish oil for cats comes in various forms, including liquid, capsules, and chews. Liquid fish oil can be easily mixed with your cat's food, making it a convenient option. Capsules can be given directly or opened and mixed with food, but they might be more challenging to administer. Chews are often flavored and can be given as treats, which might be more appealing to some cats. Consider your cat's preferences and how easy it is for you to administer the supplement when choosing the form.
Dosage and ConcentrationThe dosage and concentration of fish oil are important to ensure your cat gets the right amount of omega-3 fatty acids. Products will have different concentrations, so it's essential to follow the recommended dosage based on your cat's weight and health needs. Higher concentration products mean you can give a smaller amount to achieve the desired effect. If your cat is small or you prefer giving less volume, opt for a higher concentration fish oil.
Flavor and PalatabilityFlavor and palatability can make a big difference in whether your cat will accept the fish oil. Some fish oils are flavored to make them more appealing to cats. If your cat is picky, you might need to try a few different flavors or forms to find one they like. Ensuring the fish oil is palatable will make it easier to incorporate into your cat's daily routine.
