FeliwayOptimum 30 Day Cat Calming Odourless Plug In Pheromone Diffuser Starter Kit, 48ml - Helps Solve Signs of Stress in Cats & Kittens, Veterinary Recommended, Drug-free, Clinically Proven

Great product for creating a calming environment for a nervous cat. Quite expensive but the product is effective.

I’ve written reviews on this before it works well for stressy cats in the house hold. I use this with my cat. It doesn’t make any noise and needs refills being placed once a month. But definitely worth it in my opinion and I work as a feline only vet nurse at times and also recommend this to clients.

Cat had been struggling with UTI's, felt this could be caused by stressed. Thought it was worth trying along with some other stuff. Not sure it worked but 'touch wood' she hasn't had one since. Have on repeat subscription as its worth it even if helping a little to clam the cats. Smell is mild, at least to humans. Seems to be working well. No noise.

We’ve tried a few calming products for our rescue cat, but nothing has worked quite like FELIWAY Optimum. Before using it, she was constantly jumpy—hiding under furniture, hissing at sudden noises, and even avoiding our other cat. It was stressful for everyone in the house.Within just 3–4 days of plugging this in, we noticed a visible difference. She started coming out of hiding more often, playing gently, and even curling up near us to nap—which never happened before. It’s like she finally feels safe and relaxed.The diffuser is easy to set up, has no noticeable odor, and one refill lasts about a month. We’ve kept it in the main living area and it seems to cover the whole space well.If your cat is anxious, territorial, or adjusting to a new environment, I’d honestly recommend giving this a go. It’s not magic, but it’s close.

Didnt notice any behaviour change they still hate each other

I have been buying these on and off for years. I am taking my cats with me on a 3 week stay, I find these help to settle my cats quickly and they aren’t acting out. There is zero smell to them, which I am very happy about. Additionally, they last the full 30 days unlike other brands. One thing I would watch out for is occasionally I have noticed what looks like burn marks on my plug socket, but it wipes always.

Calms the cats down. Recently moved house so needed help with their stress levels. Would have bought 2 but expensive.

I purchased the Feliway Optimum Diffuser while blending two households, bringing a total of four cats together. My goal was to help reduce aggressive behaviors, spraying, and general stress as the cats adapted to the new environment.Pros:• Noticeable improvement in cat behavior—less fighting and territorial actions• No detectable scent for humans, but it visibly calmed the cats• Effective for all four cats, making it a good general stress relieverCons:• Cats did not become best friends, but they tolerated each other better• Range is limited, requiring one diffuser per level of the house, which adds up quickly• Monthly expense, as each diffuser lasts about a month• For more targeted stress relief, the spray version might be a better choice
