My one-year-old tabby started spraying and peeing outside the box. We've been using TheraPet for nearly 6 months now. I truly recommend it. She's now using her litter box appropriately and seems so much happier and at ease.

I have a 13-year-old Siamese cat. She thinks she's still a happy little kitten, but her constant scratching said otherwise. She's been around TheraPet diffuser for a few months, and her excessive scratching has noticeably
decreased. She's calmer and more relaxed now, it's like she's her old self again.

You won’t regret getting this, Helped our Cat!

Our female was upset after our basement flooded, which was where the litter box resided. She decided she was going to begin urinating on concrete floor! This is not cool. After vet trips and prophylactic antibiotics for possible UTI, we decided this was all behavioral. Tried many products. Was mopping the floor daily. Hate cat pee smell! Cousin suggested therapet. Thank Goodness, NO MORE peeing on the floor! 🙏🏻🙏🏻 Kitty even seems to be more amenable to our dogs!

Gave my aggressive cat a whole new outlook on life.

My cat could not be held or petted without trying to bite. She would get so wound up, she would relieve stress by running laps back and forth down the hall from BR to den. I felt so bad for her. Would play the 'fishing' game for hours each day just to help her release up all that pent up stress and energy.
After moving to a new city, I took her to a new vet for her shot updates... a practice exclusively dedicated to cats. As soon as i walked in my cat was calm, let us pet her, let the vet look at her teeth - and all without a hint of aggression. That's when I noticed they had therapet in every outlet. Wow. I came home and immediately ordered 8 atomizers for my living/dining room, kitchen and BR. Have multiples in the larger rooms. Bless her heart, she is finally close to being a normal cat. Still does not like to be held very long, but at least she doesn't try to bite me when I happen to pet her. Worth every nickel just to see her finally able to relax.

Life saver

I'm so happy I took a chance on this product. It has calmed down my 3 brother cats, much less fighting, scratching and bullying. Can't live without them.

Great for cat anxiety!

Our kitty was getting UTIs that the Vet suspected was caused by stress. This plug-in has made all the difference. She is calmer and even plays with her brother more.

Ww3 turned into Peace, love, and cuddles

Over the course of the last few years our three female cats (including the twins aka the Hissters) turned our house into a battleground. Scratched noses, hissing, you name it. I bought this diffuser a month ago and well...I'll let my pic tell the story. This stuff worked wonders for us. I highly recommend it.

Life saver when you introduce a new cat in your family

Therapet diffuser has been a true lifesaver in our home! We adopted a new cat, our existing cat (a flame point Siamese) was not happy at all with her new brother, she often expressed his disapproval with some not-so-friendly gestures. However, since we started using therapet for cat, it's like a miracle has happened. On the very first day, we noticed a remarkable change. Our cats could stay together in the condo without any aggressive behavior. Day by day, they've been getting closer, I won't say they are the best friends, but they get along well and play a lot. therapet diffuser has created a peaceful and harmonious environment in our home, and we couldn't be happier with the results.
If you're introducing a new cat into your household or dealing with cat conflicts, I highly recommend giving this a try.
I'm attaching pictures of my two cats sleeping very close and very comfortable.

Will my dog or people in my home be affected by TheraPet?

Since pheromones are species-specific,, you don’t have to be worried about dogs, other animals or humans being affected by the TheraPet diffusers.

What are the ingredients?

Pheromones are a mixture of fatty acids. Our products also contain a solvent, which helps dissolve the pheromones so they can be sprayed or diffused.

How long will it take to see results?

For the diffuser, you will start to see your cat become calmer and more relaxed over the course of at least seven days of continuous use.

What kind of plug does this diffuser use?

Based on your shipping destination, we'll automatically send you the appropriate plug. So, if you order from the US, you'll get a US plug; if from Australia, an AU plug, and so on.

Where should I use the diffuser?

The plug-in should be used in rooms where your cat spends most of its time. Avoid using outlets that are under windows, near air vents or close to doors as drafts will impair the ,proper diffusion of the pheromones. DO NOT plug the diffuser into a power strip or surge protector. The vial should always be directly below the plug-in unit for proper diffusion and to prevent leakage. To ensure the vial is always below the plug-in unit, there is a swivel function on the prongs for outlets with horizontal orientations.

When should I use the diffuser?

The diffuser should be used around your home continuously when you notice your cat displaying signs of stress such as: spraying, hiding, fighting, peeing outside the litter box, and scratching. The diffuser will help your cat feel more comfortable when unexpected disruptions in your life occur such as visitors, storms, or loud noises.

Is the smell normal?

The pheromones are diffused when the plug-in unit heats up. As with any heating element, a slight smell may be present and is totally normal. If you find your diffuser has a stronger smell, please call us and we will be happy to troubleshoot with you!

Should I unplug the diffuser at night?

To keep the good vibes flowing, you should keep your diffuser plugged in at all times. If you notice your diffuser collecting dust, please unplug and follow the cleaning instructions in the user manual found in every box.

How often should I replace the diffuser?

We recommend replacing the refill vial every 30 days or when the liquid runs out. The plug-in unit should be replaced after 6 months of use or after you have used three refill vials (whichever comes first!)
