FELIWAY Optimum is a new, patented pheromone discovery, and is the best FELIWAY answer to help reduce the most common signs of stress in cats. It helps with more signs of stress, in more situations, and calms cats better than ever; it helps reduce scratching, urine spraying (peeing), tensions & conflicts among cats, general fears, and reactions to changes. This new discovery, backed by FFELIWAY’s 25+ years of feline stress expertise, delivers advanced calming messages, helping your cats feel more comfortable at home than ever before. When surveyed, 93% of cat owners reported enhanced calming for their cats when using FELIWAY Optimum. FELIWAY Optimum’s heated diffuser and refill provide calming pheromones continually for up to 30 days in a 700 square foot area. We recommend using an additional diffuser if the room is bigger than 700 square feet. We recommend plugging in the FELIWAY Optimum diffuser in the room where you cat spends the most time, or where conflict among your cats happen most frequently. Try not to plug the diffuser under items (e.g. shelves) or close to objects (e.g. behind curtain or doors) as this affects efficacy. We do not recommend plugging your diffuser in near your litterbox or in a hallway – while your cat may frequent these places, they likely do not spend as much time in these places as you’d think. If your litterbox is in the room where your cat spends the most time, you will want to plug your diffuser into that room. Use FELIWAY Optimum each month to create a constant calming environment. Check the diffuser and refills monthly; you’ll want to replace the refill each month, and replace the diffuser head twice a year (every six months) to guarantee the best effect. Make sure to only use a FELIWAY Optimum diffuser with a FELIWAY Optimum Refill. The diffuser is not compatible with refills from other brands, and the FELIWAY Optimum vial should not be used with other diffusers. Never use a diffuser or refill of another brand with a FELIWAY produ

Hit and miss, but a great product
I tried this with a very territorial male and neutered cat who would spray. It didn’t do a thing for him and he peed a lot. Ugh.HOWEVER. After he passed, I got a little kitten who I believe was picked up from being a stray. She peed on our couch and bathroom rugs repeatedly. No UTI. I tried this product one more time for her and it works like a dream. No more peeing outside of the litter box. I can’t smell it but the feliway seems to calm her. She’s stopped peeing outside the litter box and my other cat sniffs the diffuser sometimes too. Seems hit and miss, but I think it’s worth a shot if your kitty is peeing out of the litter box! I’d rather buy this than putting her on kitty prozac! (Included: my girlie, Saffy Lynn)

Works great – but expensive
This cat calming product works well for our cat. They last about a month which makes them pretty expensive. We have a lot of outdoor cats around and I think this helps our kitty stay calm. It’s exactly what our vet uses in his clinic.

Didn’t work for me but…
did nothing for my cat but I believe it would work for others. I now put a puppy pad in an extra, empty litter box , near the other littler boxes, and he goes to that instead of peeing around the room.

It gets expensive and did not work with my cats.
Maybe this would work with other cats, it did not with mine.

Bummed, takes edge off?
Why did you pick this product vs others?:Worked on 2 of 3 of my cats. My boy it didnt affect him at all and his cat tree is next to the darn thing *rolls eyes*. I bought it for him intentionally and was really hoping it would work for him cuz he needs it the most. But he continues to hide, pee everywhere and now hes pooping ugh. I feel like its worse for him.Other two girls are sweeter, Onyx, my oldest usually tolerates our one year old pug but now she face boops the pug and cuddles together on my lap. Cali who’s usually skiddish but sweet is less skiddish and hella lovey. Her attitude is a 10/10. But she was perfect to begin with LOL.
