Helps with more signs of stress and calms cats in more conditions. Reduces scratches, urine sprays, tension, conflict, general fear and reactions to change. Backed by FFELIWAY's 25+ years of cat stress expertise, this new discovery provides an advanced calming message to help your cat stay more comfortable than ever. Research shows 93% of cat owners reported that cats have increased calm while using FELIWAY Optimum. FELIWAY Optimum heating diffuser and refills provide soothing pheromones for up to 30 days with a range of 150 square feet. If the room is over 150 square feet, we recommend using an additional diffuser. We recommend plugging the FELIWAY Optimum Diffuser in rooms where cats spend the most time or where conflict between cats are most frequent. Do not insert the diffuser under items (i.e. shelves) or nearby objects (i.e. curtain or behind door) will affect the effect. We do not recommend plugging the diffuser near the toilet or in the hallway - cats may go through these places frequently, but don't spend too much time you think. If your cat has a toilet in a room where you spend the most time, plug the diffuser into the room. Every month you use FELIWAY Optimum to always create a calm environment. Check your diffuser and refill every month. Replace the refill monthly, replace the diffuser head twice a year (every 6 months) to ensure the best results. Only use the FELIWAY Optimum Diffuser with FELIWAY Optimum Refill. This diffuser is not compatible with other brand refills. FELIWAY Optimum Vials should not be used with other diffusers. Never use refills for FELIWAY products with diffusers or other brands. Each FELIWAY diffuser comes with a plug to match your local electrical system. Do not use this diffuser with countries or adapters with different voltage. Serious security concerns may occur. Before plugging the plug, please make sure the diffuser has a fitting plug that fits your country Review: 愛猫の夜泣きがひど苦、寝不足気味。 藁にもすがる思いで、本品を購入。 効果不安はありましたが、夜泣きが落ち着いてきました。 他の猫やヒトへの影響はわからないですが、少なくとも我が家の猫には効果があったようです。 Review: 猫が病院から帰ってから落ち着きがなくなり粗相をいろんな所でしてしまったりしていましたが、１週間程で落ち着きました。 効いているように思います。 ## Features - FELIWAY Optimum is the best FELIWAY response for reducing common signs of stress in cats, such as scratching, urine spraying, tension, confrontation between cats, fear, and reactions to changes, with a new pheromone discovery - 93% of cat owners reported increased calmness, with an average satisfaction rating of 9.1 out of 10 - FELIWAY Optimum helps cats with more signs of stress and calms cats in more situations FELIWAY is supported by over 25 years of expertise in cat stress - The FELIWAY Optimum heating diffuser covers up to 150 square feet Plug in the diffuser with the air vent raised For best results, place the diffuser where cats spend most of their time - avoid inserting the diffuser under shelves, doors, curtains or behind furniture - The starter kit includes 1 diffuser head and 1 vial Use only FELIWAY Optimum diffuser and FELIWAY Optimum refills (not compatible with other brands) To maximize the effect, replace the vial once a month and the diffuser every 6 months ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097W651NJ | | Additional Features | Pet Friendly, Silent Operation | | Amazon Bestseller | #30,273 in Health & Personal Care ( See Top 100 in Health & Personal Care ) #47 in Aromatherapy Diffusers | | Automatic Shutoff | No | | Brand Name | FELIWAY | | Capacity | 48 Milliliters | | Color | translucent | | Coverage | 150 square feet | | Customer Reviews | 3.9 3.9 out of 5 stars (18,708) | | Floor Area | 700 Square Feet | | Global Trade Identification Number | 00850002593105 | | Included Components | Diffuser Kit (1 Diffuser, 1 Vial) | | Item Type Name | Diffuser Kit | | Item Weight | 136 g | | Manufacturer | Feliway | | Material Type | Plastic | | Model Name | Feliway Optimum | | Model Number | D92110K | | Power Source | Battery Powered | | Recommended Uses For Product | Home | | Scent Name | Unscented | | Shape | Square | | UPC | 850002593105 | | Unit Count | 1.0 Count | | Wattage | 1 W | ## Product Details - **Brand:** FELIWAY - **Color:** translucent - **Material:** Plastic - **Recommended Uses For Product:** Home - **Scent:** Unscented ## Images ![Optimum Cat Calming Pheromone Diffuser 30-Day Starter Kit (48mL) Translucent - Image 1](https://m.media-amazon.com/images/I/71j6M4KW9xL.jpg) ## Questions & Answers **Q: Is it normal that the green light was on just for few hours but the is not there anymore? I cannot tell if it's working or not** A: Mine stays on all the time. If it's not warm to the touch and the light is off it's probably not working. **Q: I adopted a feral kitten a year ago and she hates loud noises so she hides during the day will this help?** A: I have the same issue. At first, Feliway worked to reduce stress in my rescue cat who hides from me most of the time; no loud noises and I live alone. However I highly recommend using the Feliway diffuser together with the Royal Canin Calme food. You can purchase that through your veterinarian. **Q: I just received mine and it’s making a smell like a hot glue gun. It’s very strong. Is this supposed to happen or is this on defective?** A: Mine started smelling the same and I looked at the inside and the plastic interior had melted. Super scary. **Q: Does the diffuser still work if the green light isn’t lit but is warm to touch?** A: I don't know. I don't know if there's a way to turn off the green light. I thought of putting tape over it, but was worried it would get too hot. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***ー on January 14, 2026* 愛猫の夜泣きがひど苦、寝不足気味。 藁にもすがる思いで、本品を購入。 効果不安はありましたが、夜泣きが落ち着いてきました。 他の猫やヒトへの影響はわからないですが、少なくとも我が家の猫には効果があったようです。 ### ⭐⭐⭐⭐⭐ Review *by A***ー on January 10, 2026* 猫が病院から帰ってから落ち着きがなくなり粗相をいろんな所でしてしまったりしていましたが、１週間程で落ち着きました。 効いているように思います。 ### ⭐⭐⭐⭐ Fits loosely in Japanese outlet *by K***E on November 9, 2025* This is for a Japanese outlet but it still Fits loosely in the outlet.
