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.

Good product LONG shipping time

"My cat seems to benefit from the product, but it took a month to arrive. No explanation and no response to inquiries."

Karen F. (3/5)

NOT QUITE SATISFIED!! BUT STILL TRYING!!

"YES THE PRODUCT DOES WORK WELL FOR CALMING BOTH CATS!! WE HAVE A BASEMENT A FIRST FLOOR AND A SECOND FLOOR!! ONE IS PLUGGED IN AND PLACED ON THE FIRST FLOOR DIRECTLY IN LINE WITH THE SECOND FLOOR LANDING AND HAVE NOT HAD A ISSUE WITH URINE SPRAY ON EITHER FLOOR EXCEPT THE SECOND FLOOR ONCE SINCE WE STARTED USING YOUR PRODUCT!! WE HAVE A SECOND ONE PLUGGED IN OUR BASEMENT WHICH WE ARE FINDING THEY ARE HAVE URINATED STILL IN A FEW PLACES!! WE WILL TRY MOVING THE PRODUCT TO A DIFFERENT LOCATION AND PLUGGING IT IN TO SEE IF IT MAKES A DIFFERENCE!!"

ERIC S. (3/5)

Never received order

"I have contacted customer service over ten times and still haven’t received my order FEL133976. Your customer service is pathetic! Can someone please help?"

Melissa M. (1/5)

Didn’t do anything

"I bought the FELIWAY Diffuser for my cat to try to help her calm down after our move and reduce her spraying. Didn’t do anything. There’s still piss everywhere."

Samantha S. (1/5)

No change in behavior

"I have 3 cats 3, 13, 16 in ages. The oldest is a fixed female. The youngest is a neutered male, as is the 13 y/o. None of them particularly care for each other, but the boys really dislike the female, especially our youngest he tortures her. It is to the point that she won't use any of our 6 litter boxes for fear of being trapped and attacked. I put the defuser where the female cat prefers to be, but since then she hates that spot, and if anything is MORE abused because she is more likely to be seen by the boys. Maybe the chemicals effect some cats differently, but this product seems to have zero positive effect on any of my 3 cats,not calming, dose not deter fighting, or going on the floor. So for US this product is just an expensive addition to other useless purchases. Side note, the spray also does nothing for them."

Joshua C. (1/5)

Not for kittens

"Kitten developed a cough and wheeze (not near the plug). Once I unplugged it, all cleared up."

Thea S. (1/5)

"Most definitely calms and helps my anxiety ridden cat relax. She is like a different cat on the day I change the plug ins. I use the optimum diffuser."

Holly (5/5)

Kristen b. (5/5)

Awesome

"I HAVE A DEVIL CAT OR THATS WHAT WE CALL HER. SHE HAD THE HABIT OF JUST LYING IN WAIT AND GRAB, SCRATCH OR BITEING WHICH PUT ME OM THE HOSPITAL OPNCE. AFTER I USED FELIWAY WHAT A BIG DIFFERENCE. SHE IS MUCH CALMER NOW. SHE CAN STILL ATACK, BUT NOT AAS OFTEN AND USUALLY THERE IS A REASOMN FOER IT."

Beatrice H. (5/5)
