I feel like my cat is getting used to the Classic and it doesn’t calm him as much as it used to.** A: I have used the multi- cat on & off for years with excellent results, but I wanted to give the optimum. Not sure if it's necessarily better (both are equally effective for us) but it definitely works faster. For your situation, switching to a different formula is worth a shot. **Q: Can the same diffuser i have for the multi cat be used for this?** A: The instructions actually say to not use another brands diffuser for the refills, and not to use another brands refills in the diffuser. It does not specifically say to not use another one of their own diffusers. I will say I used my old multi cat diffuser and it was fine and worked well. **Q: Can this be plugged in 220v or just 110v?** A: I believe it would only be safe to use in 110 volt. **Q: Can you use this in a dog friendly home with two cats?** A: You may want to contact Feliway directly for the best answer. That said, the cat pheromones shouldn't effect your dog. If your dog is a chewer I recommend plugging in somewhere the dog can't reach it since it's ball shaped (or train the dog that it's strictly off limits). ## Frequently Bought Together - FELIWAY Optimum 3 x 30 Day Cat Calming Refills for Pheromone Diffuser, 3 x 48ml Value Pack - Helps Reduce Common Signs of Stress in Cats & Kittens, Enhanced Calming - FELIWAY® Classic Cat Calming Spray, 60ml - Comforts Cats at Home and On the Go and Helps to Calm During Travel --- ## 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.co.uk/products/438754313-optimum-enhanced-calming-pheromone-30-day-refill-3-pack](https://www.desertcart.co.uk/products/438754313-optimum-enhanced-calming-pheromone-30-day-refill-3-pack) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-20*
