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 Comfort Zone Multi Cat Calming Diffuser Refills are a drug-free, fragrance-free solution designed to reduce tension and aggressive behaviors in multi-cat households. This product uses calming pheromones to help manage issues like swatting, scratching, and fighting. The refills are compatible only with Comfort Zone diffusers, which are reusable for up to 12 months. Each refill lasts about 30 days, providing up to six months of continuous calming support with the included six-pack value set.

The diffusers effectively cover up to 400 square feet, making them suitable for larger rooms where your cats spend most of their time. Safety is a key aspect, with the product meeting Intertek electrical safety and certified to UL standards, and an automatic shut-off feature to prevent overheating. While the diffuser is easy to use, it requires proper placement—upright and not obstructed by furniture for optimal performance.

Users should note that the product might not work with other brands’ diffusers and must be replaced monthly for consistent effectiveness. Additionally, the lack of fragrance might be a plus for some, but it could also mean it's less noticeable when it's working. This calming solution may be particularly beneficial for households with more than one cat experiencing behavioral issues.

The FELIWAY Optimum Enhanced Calming Pheromone is a 30-day refill designed to reduce stress-related behaviors in cats, such as scratching, urine spraying, and excessive hiding. As a non-sedating and drug-free solution, it releases pheromone analogs to provide a natural, reassuring message to cats, helping them feel more at ease. This product is easy to use—simply plug the diffuser into an open outlet with good air circulation, and it will work continuously for up to 30 days.

It’s important to use the FELIWAY diffuser with its specific refills for optimal results. One diffuser covers up to 700 square feet, and it should be replaced every six months, with refills changed monthly. Backed by over 25 years of research and recommended by vets, it’s a reliable choice for many cat owners.

However, it may not be universally effective for all cats, and the need to replace refills and diffusers regularly could be a recurring cost. Additionally, while it is safe for cats, humans, and other pets, it carries a specific scent (Mimosa) that may not appeal to everyone. This product is most beneficial for cat owners dealing with noticeable signs of feline stress in their homes.
