10 Best Calming Products For Cats 2025 in the United States

VetriScience Composure Pro is a calming chew designed for both cats and dogs, aimed at reducing stress and promoting relaxation within about 30 minutes, with effects lasting up to four hours. It uses a blend of ingredients like Colostrum Calming Complex, vitamin B (thiamine), and L-tryptophan to support your cat's brain function and help soothe anxiety caused by loud noises or restlessness. The chews come in a chicken flavor, which should appeal to many cats, making it easier to administer. Dosage is flexible, based on your pet's weight and needs, ranging from half a chew to two chews per dose.

The product is made in a certified facility, free from artificial flavors, and carries a quality seal, which increases confidence in its safety for your cat. While the supplement is convenient and tasty, the calming effect is temporary, lasting only a few hours, so it may require multiple doses depending on the situation. Because it’s a supplement, results can vary among cats, and some pets might prefer other forms like sprays or diffusers.

This product suits cat owners looking for an easy-to-use, short-term calming aid that is safe and backed by science, especially helpful during stressful events like fireworks or travel.

The Purina Pro Plan Veterinary Supplements Calming Care Cat Supplements are well-regarded, with the brand being the number one veterinarian-recommended cat probiotic. This product uses a proprietary probiotic strain (BL999) designed to help manage stress and anxious behaviors in cats. It comes in a powder form with a liver flavor, which might appeal to many cats, making it relatively easy to administer by mixing it with their food.

The product claims to support positive behaviors, like playing and seeking social contact, while also helping to manage stress-related hormones like cortisol and support a healthy immune system. Each box contains 30 packets, enough for a month's supply, as it is recommended to give one packet daily. However, it can take up to six weeks to notice the full effects of the supplement, which might require some patience from pet owners.

Safety precautions indicate that this supplement is for cats only and should be used under the supervision of a veterinarian, particularly because the safety for pregnant cats or those intended for breeding has not been established. This could be a good option for cats that are prone to anxiety or stress, but it might not be the best fit for owners looking for more immediate results or those with pregnant cats.

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.
