Indoor

The 3 a.m. hack-hack-hack… then another wet hairball on the carpet. Indoor cats groom all day, and all that swallowed hair has to go somewhere. ivvi Indoor is one creamy, real-tuna lickable sachet a day — a fiber blend that helps the hair pass through her gut and out the right end, instead of back up onto your floor.

  • Supports the natural elimination of swallowed hair — psyllium, inulin and cellulose fiber help carry hair through her digestive tract and out in the litter box.
  • Supports smooth, regular digestion — soluble and insoluble fiber plus prebiotic inulin help keep things moving comfortably.
  • No petroleum paste, no fight — a clean, fiber-led formula in a real-tuna cream, not the sticky mineral-oil gels cats spit out.
  • A picky-cat favorite — a creamy treat made with real tuna that most fussy cats happily lick right up.
  • One easy sachet a day — no pills, no mess; just a daily lick that becomes part of your routine together.
Risk-free: 180-day money-back guarantee if you don't see results.

Psyllium Husk

Our headline fiber — a soluble, gel-forming fiber that bulks and softens stool to help carry swallowed hair smoothly through the digestive tract and out the right end.

indoor-ing-2

Inulin

A prebiotic fiber that feeds the good bacteria in your cat's gut, supporting a healthy microbiome and smooth, regular digestion.

indoor-ing-3

Malt

Traditionally used in hairball care, this maltose-rich malt helps lubricate the passage of swallowed hair — and adds the rich, satisfying taste cats come running for.

indoor-ing-4

Slippery Elm

A traditional botanical whose natural mucilage is long used to support a soothed, comfortable digestive tract as hair passes through.

indoor-ing-5

Cellulose

An insoluble fiber that adds gentle bulk to support normal, well-formed stool and everyday digestive regularity.

Salmon Oil

Rich in omega-3 EPA & DHA, salmon oil supports a healthy skin and coat — helping reduce the excess shedding that means less loose hair for your cat to swallow.

Customer photo review of Indoor

My kitties, Ragdolls which have long dense fur, love it and their coats look silky and shinier. It’s hot and humid here in SW and we’ve not had any hairballs since I started giving ivvi to my fur babies.

Customer photo review of Indoor

Indoor

Love that my cat has been enjoying this as a treat but with the added benefits!

Indoor

I have two cats. One or both throw up fairly often. Each has long hair. Brushing doesn't help all that much, but thankfully, knock on wood, there have been no purges since purchasing your product. They both love the flavor.

Indoor

After trying multiple hairball medicine for my 2 cats, this is the only one that they actually like! In fact, they love it! I'm so happy that I found something that they will not only eat, but is good for them. Thank you!!!

Indoor

I just started giving it to my cat. She loves eating it. I am hoping it helps stop the vomiting she does almost daily.

Indoor

I have pickiest Ragdoll cat. She also has long fur so constantly gets furballs. She won’t eat anything, I have wasted so much money buying products that I give away. She lapped this up with little hesitation. I’m so happy. I hope it helps her to pass the furballs and feel happier and healthier.

Indoor

Mini gobbled her 1st tube, is now delicately wiping her whiskers. Cut tube open and she inhaled every last speck. Not a fan of Churu Indoor Care which Kitty #2 loves, so I'm happy she loves this flavor. Hairballs begone !!

Indoor

It may be a little soon to evaluate how well this works. I have only given her two tubes of it. The encouraging thing though is that she ate them both and she is a very finicky eater at best. Fingers crossed that it works for the little darling since I am so dismayed at how much she has been throwing up hairballs this summer.

Indoor

Sasha loves this! She asks for it everyday at 3:00 in the afternoon. Only have used it for a week and no hairballs. She was having them about every 3 or 4 days and it was very difficult for her. Thank you from Sasha and myself for a great product!

Indoor

My cats love the taste and so far, no hairballs. I'm impressed.

Indoor

One cat likes it, one doesn’t

Indoor

My cat loves it and that's what matters.

Indoor

My cat Nicho loves it!

Indoor

It works great!

Indoor

This is a really good product, and my cats absolutely love it! I just wish they would drink more so they could get the full benefits from it. They’re seniors and eat mostly soft food, but they simply don’t eat enough to get the hydration they need. One of my cats started passing mostly hairballs during the first few days, and they were very dry and hard. It was honestly scary to think that this may have been contributing to him not going to the bathroom regularly. He had become depressed, wasn’t eating much, wasn’t very active, and just didn’t seem like his happy self anymore. Then, after passing the hairballs, it was like a switch flipped. He became his happy self again! ❤️ He’s still passing stools that are harder than normal, which I believe is likely because he isn’t drinking enough, but seeing the difference in his mood and overall demeanor has been amazing. I’m very happy with this product and will definitely continue using it. I just wish I could get my senior cats to drink more! 🐱❤️

Indoor

My cat loved it. Where can I get more?

Indoor

So far Lucy loves the taste (here's hoping it continues), but it's too soon to tell if it will make a difference. Time will tell and I have high hopes.

Indoor

The product is fine, it's just that my extremely picky cats don't like it! One cat won't have anything to do with it, and the other will eat a little bit and then walk away

Indoor

A miracle would. Work! My cat will not touch it after many tries. Don't send any more

Indoor

Both cats love it. ❤ It seems there dandruff is becoming less visible, coat is shiny.

Indoor

Cat loves this

Indoor

She ate the indoor on her wet food immediately that had her Dasequin in it which she does not care for. I am very encouraged that I can now get the Dasequin in her for her joints which is a big relief and I gave her only a small amount of the indoor on her food.

Indoor

Mittsy loved it and licked it all up. Yippee!

Indoor

The product seems to be working however I wondered if that company was ever going to ship the product.

Indoor

The only thing wrong with it is I found out my cat doesn't like tuna. Sorry about that.

Indoor

My cats love these. Easy to open - my cats lick it straight from the tube, but you can also squeeze it onto their food.

Indoor

The cats love the paste, and it clearly reduces hairball formation!

Indoor

My tomcat used to throw up regularly and cough up fur. Since I give him half a sachet every day, he hasn't thrown up once!

Indoor

My long-haired cat vomits a lot and refuses this kind of product - but he accepts this one and loves it. Finally an anti-hairball that works, phew!

Indoor

The cats love it - and no more hairballs or gagging fits.

Indoor

The cats licked it very happily... it's just a bit too expensive for me.

Indoor

Very effective at clearing the hair my long-haired cats swallow while grooming, and even the fussy ones adore the creamy treat. I recommend it.

Indoor

My cats have abandoned their old churu treats for these. They're crazy about them.

Indoor

Not palatable for my cat - just the smell makes him walk away.

Indoor

My cat licks the tuna sticks like a popsicle. The malt, psyllium and inulin really get her digestion going - after two weeks I'm finding far fewer 'carpet sausages.'

Indoor

Effective support against hairballs - our cat loves it. We tested it through the shedding season when she really struggles with hairballs.

Indoor

It works - reduces hairballs noticeably, especially helpful during the coat change.

Indoor

I've used these products before and always got on well, so I tried the anti-hairball version - my cat adores it. The cream smells appetizing and she licks it right up.

Indoor

My cat refuses the lick.

Frequently Asked Questions

Everything you need to know about the ingredients, quality, and care behind our award-winning treats.
How much should I give my cat each day?

Just one sachet a day — that's the full daily serving. Each box has 30 sachets for a one-month supply. You can offer it straight from the sachet as a lickable treat or squeeze it onto her food; most cats look forward to it once it's part of the daily routine.

How soon will I see fewer hairballs?

Fiber works gradually, not instantly — it needs to be in her system every day to help carry swallowed hair through. Many owners notice fewer hairballs and smoother litter-box trips within a couple of weeks of consistent daily use, but every cat is different, so give it a fair, steady run before you judge it. It tends to help most when you keep it going through shedding season.

My cat refuses those petroleum hairball gels. Will she eat this?

This is exactly where ivvi Indoor is different. Instead of a sticky, mineral-oil paste most cats spit out, it's a creamy, real-tuna lickable — the kind of treat fussy cats happily lick right up. We'll still be honest: no single flavor wins over every cat. If yours turns up her nose, our 180-day money-back guarantee means you can try it completely risk-free.

How does it actually work on hairballs?

Indoor cats swallow a lot of loose hair while grooming, and most of it should simply pass through and leave in the stool. ivvi Indoor combines soluble and insoluble fiber — psyllium, inulin and cellulose — with traditionally-used malt and slippery elm to add moisture and gentle bulk, supporting the natural elimination of swallowed hair through the digestive tract instead of it clumping in her stomach. Salmon oil supports a healthy coat, so there's less excess hair to swallow in the first place.

Is it safe? Are there any cautions?

It's a clean, fiber-led daily supplement made with real tuna, but introduce it gradually so your cat's stomach can adjust to the added fiber, especially if she has a sensitive tummy, and always offer fresh water alongside. As with any supplement, check with your veterinarian first if she's pregnant, nursing, very young, or on any medication. And if your cat ever seems genuinely unwell — lethargic, refusing food, or retching repeatedly without bringing anything up — please see your vet, as that can signal something a supplement isn't meant to handle.

What's actually in it, and how clean is it?

A fiber blend of psyllium husk, inulin and cellulose, plus traditionally-used malt and slippery elm and omega-3 salmon oil — all in a base of real tuna. No petroleum or mineral-oil laxatives, no meat by-products, no artificial flavors and no artificial colors, so it's a daily treat you can feel good about giving her.

What's your return policy?

Every order is backed by our 180-day money-back guarantee. Give it an honest try, and if you or your cat aren't happy for any reason, just reach out and we'll make it right — no hassle. That way the only thing you have to lose is one more hairball on the carpet.
