Details

Plug-in diffusers stay in one room. Sprays wear off in hours. Your cat doesn't stay put.

The Lullacat Calm Collar slowly releases a calming scent right under your cat's nose, so it goes everywhere they go: under the bed when guests arrive, into the carrier on the way to the vet, the new house after a move.

  • Breakaway safety clasp: releases if the collar catches on something.
  • One size fits all cats: 15 in (38 cm), cut to fit.
  • Lasts up to 30 days: swap in a fresh collar each month.
  • Natural plant extracts: lavender, chamomile and lemongrass scent. No citronella.
  • Waterproof and soft: light enough to forget it's there.
  • No plug-in, no pills: nothing to remember each day.

Comes in a resealable aluminum tin. It is not a flea or tick collar.
How to use it
  1. Open the tin and let the collar air out for an hour.
  2. Fasten the breakaway clasp with a two-finger gap: snug, never tight.
  3. Trim the extra, leaving about 2 inches past the clasp.
  4. Swap in a fresh collar every 30 days.

Tip: put it on 3 to 5 days before a vet visit, a trip or guests arriving. For cats over 12 weeks old.
Shipping and returns

Free US shipping on 2 or more collars. Orders ship within 1 to 3 business days, with tracking, and arrive in 7 to 15 business days.

30-day money-back guarantee. If your cat isn't calmer within 30 days of delivery, email us for a full refund. No need to send it back.

    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.

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.
