I have 2 brand new plugs, so hoping I can use them with these.** A: Yeah! Thats what I do. I chop and change the refills around every few months using the same adaptor :) **Q: How many of these should I put in the house. Just one? Or one in each room? Please can you advise. Thank you** A: One diffuser covers 70 square metres or 750 square feet - so depending on your house size - but I feel one on each floor is good ## Frequently Bought Together - Feliway Optimum Refill 3 Pack - FELIWAY Classic Cat Calming Pheromone Spray (60 mL) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/779274527-feliway-optimum-3x30-day-cat-calming-odourless-refills-for-pheromone](https://www.desertcart.us/products/779274527-feliway-optimum-3x30-day-cat-calming-odourless-refills-for-pheromone) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-09*
