Within 24 hours of plugging this in, she started rubbing against us, meowing for attention and is currently sprawled out, belly up, purring on the sofa. So happy for her! Review: It's working!!! - We have a big alpha cat that always throws tantrums and bullying his sister. Day 1, it shows positive results. He was calm, even with the birds in the window he usually attacks, now he is just watching from afar. Aggression towards his sister now reduce to just staring to her. He stopped peeing in the sofas. Now become clingy and starts sleeping besides us in the bed.

We were tired of 3 males (all neutered) in particular not being able to tolerate being near each other and constantly fighting. I’ve had this thing running a couple of weeks now, mostly the fights have stopped all except for one cat who wants to play whilst the others don’t which sometimes ends in fisty cuffs. I can live with that, before it was constant. ## Frequently Bought Together - Feliway Optimum Refill, The Best Solution to Ease cat Anxiety, cat Conflict and Stress in The Home - 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.pt/products/305837202-feliway-optimum-refill-48-ml](https://www.desertcart.pt/products/305837202-feliway-optimum-refill-48-ml) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-10*
