10 Best Calming Products For Cats 2025 in the United States

Pet Honesty Calming Chews for Cats are designed as tasty, easy-to-give treats that help reduce anxiety and promote relaxation in cats, especially during stressful events like travel, vet visits, or separation. They feature natural calming ingredients such as L-Theanine, L-Tryptophan, Chamomile, and Thiamine (Vitamin B1), which support the nervous system and help soothe anxious behavior. The chews come in a crunchy and creamy chicken flavor that many cats find appealing, making administration less challenging.

These chews are intended for all ages and medium breeds, with dosage based on the cat's weight, and can be given daily to maintain a calming effect over time. The product is made in the USA under strict safety standards, free from common allergens like corn, wheat, and soy, and contains no artificial additives, which supports its safety profile. The duration of the calming effect can vary between cats, and some cats might not respond to supplements as expected.

The product is well-rated by many users, although individual preferences for taste and texture may differ, so it might require some trial and error. This makes these chews a natural, convenient option for cat owners seeking to ease their pet’s stress with minimal fuss, especially if their cat enjoys flavored treats and needs support in mildly stressful situations.

The FELIWAY MultiCat Calming Pheromone, 30 Day Refill, is a pheromone product designed to reduce tension and conflict between cats. It mimics a mother cat’s natural pheromones, which can help to soothe and comfort multiple cats living in the same household. This product is drug-free and non-sedating, making it a safe choice for both cats and humans. Safety is further assured as it does not affect other pets in the home.

The product is easy to use; simply plug the diffuser into an open outlet, and it will continuously release the calming pheromone for up to 30 days. However, to maintain effectiveness, the vial needs to be replaced monthly, and the diffuser every six months. This could be seen as a recurring cost and minor inconvenience for some users. The product is backed by scientific research and 25 years of expertise, with 84% of cat owners reporting a significant improvement in cat conflicts.

The compact dimensions (1.75 x 1.75 x 3.25 inches) make it a discreet addition to the home. One limitation is that it requires a specific FELIWAY diffuser, so compatibility with other brands is not an option. It is an excellent product for cat owners seeking a non-invasive and scientifically supported method to reduce tensions between their pets.

The FELIWAY Optimum diffuser uses synthetic pheromones designed to mimic natural calming signals cats give each other, making it a drug-free and non-sedating option. This makes it a good fit for cat owners looking for a safe, gentle way to reduce stress-related behaviors like spraying, scratching, and fearfulness. It works continuously for up to 30 days per vial, covering about 700 square feet, which suits most home environments with one or two diffusers. It’s simple to use—just plug into an outlet with some open space around it for best effect—and designed specifically for cats, so it won’t affect people or other pets. Users report significant reductions in common stress behaviors, which supports its effectiveness.

Because it relies on pheromones, results can vary from cat to cat depending on individual preferences and sensitivity. The diffuser must be replaced every six months and only with official FELIWAY refills, which adds some ongoing cost and limits flexibility with third-party products. Placement matters, too; it shouldn’t be hidden behind furniture or near litter boxes to work well.

While some cats respond quickly, others might take longer or need additional calming support. FELIWAY Optimum is a trusted, veterinarian-recommended calming product best suited for cat owners who want a safe, easy-to-use, and steady way to ease their cat’s stress without medication, though it requires monthly maintenance and careful placement for best results.
