How long does FELIWAY® Optimum take to work?

When using FELIWAY® Optimum, many cat parents start to see results for
their cat within the first seven days of use. However, all cats are different.
The first signs of enhanced serenity may come later depending on the duration
and severity of your cat’s signs of stress. We recommend using FELIWAY® Optimum for a period of at least one month, and ideally use it continuously for the maximum benefit.

For more information on how long all our FELIWAY® diffusers take to work, view our full guide here.

How long should I use FELIWAY® Optimum for?

Most cats benefit from the continued use of FELIWAY® Optimum to create a pleasant environment in the home, with the minimum recommended duration being one month of use. This ensures that FELIWAY® Optimum has time to take full, though you could start to see enhanced serenity in your cat much sooner.

When should I use FELIWAY® Optimum?

For the best results, it’s recommended that FELIWAY® Optimum is used
constantly or for a minimum of at least one month. Simply leave the diffuser
plugged into an electric socket 24/7 to provide ongoing support and enhanced
serenity for your cat.

You should consider using FELIWAY® Optimum in the following situations:

  • If your cat is urine spraying
  • If your cat is scratching walls or furniture
  • If your cat shows signs of stress such as hiding, reduced activity or appetite, or overgrooming
  • If you are anticipating changes to your home (e.g. moving house, renovations, redecorating your home, or arrival of a new pet or person into the household)
  • If you have two or more cats living with you and they show signs of tension (e.g. chasing, blocking, or staring) or if they are fighting?

Where should I use FELIWAY® Optimum?

For the best results, you should use FELIWAY® Optimum in the room where
your cat spends most of their time. Plug the diffuser into a properly functioning electrical socket that has clear space above it of at least 4ft (1.2m). This allows the oily vapor that carries the calming messages to rise above the diffuser in a column of warm air and into the surrounding environment.

Where should FELIWAY® Optimum NOT be used?

To ensure your FELIWAY® Optimum diffuser can work as effectively as
possible, you should avoid using it in:

  • Hallways - Cats naturally spend very little of their time in hallways, so FELIWAY® Optimum will have a reduced effect if used here.
  • Near the litter box – Likewise, cats spend very little time near their litter tray, so the efficacy would be reduced if used here. If the litter box is in the room where your cat spends the most time, there is no problem plugging it in this room.

Reviews

Noticeable results

"After almost a month I can visual relaxed state my cat is exhibiting. He used to scatter off and be hyper focused on the noises or surroundings happening around him. He handles it much better now. The change came on subtle but I would recommend trying it."

Lisa T. (5/5)

Game changer in our household

"We have 8 cats and while this did take the full month for effects to kick in (as the packaging states) we also started two of our cats in fluoxetine, changed our feeding strategy and moved into a bigger home (lol, the last one was only due to work purposes though. . . not the cats). However, there is now peace and harmony (no more staring down other cats, stalking behavior, etc). I'd highly recommend trying the Optimum formula for a multi at household."

Brittany F. (5/5)

Can't tell if it helps

"We've been using Feliway for 2 months now and I really don't know if it's helping. Maybe the two boys are fighting less, but that wasn't predictable anyway. The one who pees has been peeing even more. We've also had other changes going on at the same time so then this hasn't dampened his change-related stress. He maybe has seemed less skittish in general, and hasn't been hiding in the bed lately, even when we had many visitors including a child, though again that's hard to predict and could be coincidence. It's expensive to buy 2 a month for our size house so I'm not sure if I'll keep getting these or not."

Cassie S. (2/5)

Not working.

"I have a Bengal and she keeps attacking my other cat. It doesn't seem to work. I've moved it to different outlets. I even held it near her to see and she could have cared less about it. I've never seen her near it and I've had it for 2 weeks now."

Laura B. (1/5)

Feliway Optimum

"Love the product and the size of large 3 month supply. When the refill starts nearing the end my 3 cats start fighting and I need to change to a new one. I have 2 cats 15 years old and a young one 3 years old ( the females really don’t like each other. Feliway makes a big difference!"

Carol B. (5/5)

Peace in my house!!

"I added 2 re-homed cats to my house and it was chaos. Behavior mod is one thing but the diffusers smoothed the rough edges. No more snarling and fighting!"

Jackie S. (5/5)

this stuff works

"I got this because my daughter suggested it I have a very big nervous orange cat, and we got a kitten, I have a subscription, during the summer I paused it and the cats were not getting along as well so I turned the subscription back on even though the doors are open it still works"

James m. (5/5)

No change

"There has been no change in my cat's behavior since plugging this thing in. The only thing I've gotten was a greasy spot in the floor beneath the unit."

Marla M. (1/5)

Waste of my time and money

"The product was ineffective as far as helping my cat mark her territories. A waste of money spent, and this is based individually on the cat. My cat was not phased by it. Sorry for the negative review on this."

Denise J. (1/5)

"I was hopeful for this to help my cats, but they are still in hiding mode. I'm also concerned they the plastic cover overheats in my home."
