Ease of Use
The bottle does get oily, but I just keep wiping it down.

The FELIWAY MultiCat Calming Pheromone is a drug-free relaxer designed for households with multiple cats experiencing tension. It uses pheromone analogs that mimic a mother cat's natural calming scent, which can help reduce conflicts such as fighting and chasing. One of its strong points is its ease of use; simply plug the diffuser into an outlet and it will work continuously for up to 30 days.

This is particularly helpful for busy pet owners who may not have time to administer daily treatments. The product is also safe for both humans and other pets, ensuring a worry-free environment. However, it's important to note that the effectiveness can vary, meaning it may not work for every cat. Additionally, the product requires you to use the specific FELIWAY diffuser and refills, which can add to the cost over time.

For maximum effectiveness, the diffuser should be replaced every 6 months and each vial every month. Supported by over 25 years of research, those looking for a one-size-fits-all solution might need to explore other options if their cats don't respond to pheromones.

Buying Guide for the Best Relaxers For Cats

Choosing the right relaxer for your cat can make a significant difference in their comfort and well-being, especially in stressful situations. Relaxers can help calm your cat during events like vet visits, travel, or changes in their environment. To find the best fit for your feline friend, it's important to understand the key specifications and how they relate to your cat's needs.
Type of RelaxerRelaxers for cats come in various forms, including sprays, diffusers, collars, and treats. The type of relaxer is important because it determines how the calming agent is administered and how effective it might be for your cat. Sprays and diffusers release calming pheromones into the air, which can be great for general anxiety or environmental stress. Collars provide a continuous release of calming agents and are ideal for cats that need constant support. Treats are ingested and can be useful for situational anxiety. Consider your cat's behavior and the specific situations where they need calming to choose the right type.
Active IngredientsThe active ingredients in cat relaxers can vary, with common ones including pheromones, herbal extracts like valerian root or chamomile, and amino acids like L-theanine. This spec is important because different ingredients work in different ways to calm your cat. Pheromones mimic the natural calming signals cats produce, which can be very effective for many cats. Herbal extracts and amino acids can have a soothing effect on the nervous system. If your cat has allergies or sensitivities, it's crucial to check the ingredients list. Choose an active ingredient that aligns with your cat's specific needs and sensitivities.
Duration of EffectThe duration of effect refers to how long the relaxer will keep your cat calm. This is important because it helps you plan for how long your cat will be relaxed. Short-term relaxers, like sprays or treats, might last a few hours and are suitable for specific events like vet visits. Long-term options, like collars or diffusers, can provide continuous calming effects for weeks or even months, making them ideal for ongoing anxiety or stress. Consider the duration of the stressful situation and choose a relaxer that matches the required timeframe.
Ease of UseEase of use is about how simple it is to administer the relaxer to your cat. This is important because a product that is difficult to use can add to your cat's stress rather than alleviate it. Sprays and diffusers are generally easy to use and require minimal interaction with your cat. Collars need to be fitted properly but then work continuously. Treats need to be given directly to your cat, which can be easy if your cat likes them. Choose a product that you can use comfortably and that your cat will accept without much fuss.
SafetySafety is a crucial spec to consider when choosing a relaxer for your cat. This includes checking for any potential side effects and ensuring the product is safe for your cat's age, weight, and health condition. Some relaxers may not be suitable for kittens, elderly cats, or cats with certain medical conditions. Always read the product label and consult with your veterinarian if you have any concerns. Choose a relaxer that is specifically designed for cats and has a good safety profile.
