I don't understand how this works, but it does - it was a little creepy at first, it seemed like my cat's personality changed. i only use it when he needs to travel or when i clip his nails, but it works very well.

I loved the smell and it really works; I put it on and it relaxed me a little while later. Now I'll see if it really lasts for two months.

I need to check its effectiveness; I will make an assessment in a few days after seeing the improvements in the cat's condition.

It arrived earlier, I've already put it on to see if it works well to calm the cat's heat. Does anyone know if it works well?

Unfortunately, it didn't work with my cat, but I can't say whether the product itself doesn't work or if her case will only be resolved with medication. She is very nervous; I tried this collar before taking her to the vet. The positive aspect was that it's a very comfortable collar, my cat adapted quickly, it just didn't work to calm her down. It comes in a sealed package and is easy to put on, but it has a slightly strong initial smell.

just right for his neck, I didn't have to cut it. It has a lavender smell. My cat is still just as bad as before, the effect wasn't what I expected.

It has a very strong smell like lavender, I don't think it does anything, it just perfumes your pet's neck. I'm not going to use it, it seems toxic.

I don't notice that it calms my cat at all. Additionally, it has a very strong smell that ends up bothering me while breathing inside the car. And after wearing it for a while, even if I take it off my cat, the smell stays in its fur for several hours.

I received the order in an unprotected bag, so the order arrived damaged, the can was dented, which makes it difficult to open for that reason.

Questions
Good questions, straight answers.
How fast does it work?
Every cat is different. Some owners see a change in a day or two, others after a couple of weeks. For a known event like a vet visit or a move, put the collar on 3 to 5 days ahead.
Is it safe for kittens?
It's made for cats over 12 weeks old. It has a breakaway clasp that releases if the collar catches on something. Fit it with a two-finger gap and check the fit for the first few days.
Does it smell?
Yes, a light lavender scent. It's strongest when you first open the tin, so let the collar air out for an hour before you fit it.
How long does one collar last?
Up to 30 days. Then swap in a fresh one.
Will it fit my cat?
One size fits all cats: 15 in (38 cm), cut to fit. Fasten with a two-finger gap and trim the rest.
Is it a flea collar?
No. It does nothing for fleas or ticks. Keep using your usual flea treatment.
I have two cats. Do I need two collars?
Yes, one per cat. The 2-pack and 4-pack are the easiest way to cover a multi-cat home, with free shipping.
When will it arrive?
Orders ship within 1 to 3 business days with tracking and arrive in 7 to 15 business days. The exact dates show next to the Add to cart button.
Can I return it?
You don't need to. If your cat isn't calmer within 30 days of delivery, email us and we'll refund you in full. No need to send it back.
Our promise
Try it for 30 days, or your money back.
Put it on before the next vet visit, car ride or houseful of guests. If your cat isn't calmer, you get a full refund.
No need to send it back.
