Why nothing has worked
You've Tried Everything. The Hairballs Keep Coming.
Pastes, oils, special kibble, daily brushing. Your cat still gags, dry-heaves and leaves a surprise on the rug. That's because most remedies react after the hairball has already formed — they never stop the hair building up in the first place.
It's a cycle. And it isn't your fault — cats swallow hair every time they groom. Conventional remedies were never designed to break it.
How Hairball Defense works
The Only Thing That Breaks the Cycle.
Pastes and oils wait for the hairball to form. Hairball Defense works every day — cat grass and lecithin help swallowed hair move through the way it should.
Barley seedling powder is the same young grass outdoor cats seek out to clear swallowed hair. Indoor cats never get it — until now.
Real barley grass
A natural emulsifier that breaks down the oils binding hair together, so it moves through digestion instead of matting into a ball. No mineral oil, no petroleum.
Not mineral oil
Salmon, chicken liver and catnip in a crunchy fish-shaped treat. 5–15 a day by weight — most cat parents see fewer episodes within 2 weeks.

Which Hairball Cat Do You Have?
Some cats swallow far more hair than others. Hairball Defense is built for the ones that need it most.
Double coats mean double the swallowed hair. These cats need daily support, not an occasional paste.

Cats groom each other and swallow more hair. One jar per cat keeps every one of them covered — that's what our bundles are for.

As digestion slows with age, hair sits longer in the stomach. A gentle daily treat keeps things moving without stressing an older gut.

Outdoor cats eat grass to help hair pass. Indoor cats never get the chance. Hairball Defense puts real cat grass back in their day.

Simple Ingredients. Nothing Hidden.
A crunchy salmon treat built around the two things that actually help hair pass: cat grass and lecithin.
Young barley grass — the same thing outdoor cats graze on when they need to clear swallowed hair. Indoor cats never get it. Now they do, every day.
A natural emulsifier used in hairball remedies for decades. It breaks down the oils that bind swallowed hair into a ball, so it moves through instead of coming back up — no mineral oil needed.
The reason picky cats come running. No disguising it in food, no wrestling with paste.
Makes treat time something your cat asks for — which is what keeps a daily routine going.
Keep every treat fresh without artificial preservatives.

Your cat's Hairball Defense journey
What Happens Week by Week.
5–15 treats a day by weight. Here's what typically changes — and when you'll see it.
Your cat eats them like treats — salmon and catnip do the convincing. Inside, lecithin starts loosening hair already sitting in the stomach so it can't pack into a dense ball.
Most cat parents notice the 3am hacking and dry-heaving ease off in the first week as hair starts passing through instead of coming back up.
With the daily routine in place, hair clears steadily. By week two, most cats are producing noticeably fewer hairballs — for many, none at all.
Keep going at the label dose and buildup never gets the chance to start. Shedding season included.
*Based on customer-reported results. Every cat is different; long-haired and senior cats can take longer.
Real cats, real results

“No more gagging, no more vomiting. The difference was night and day.”
“Over a month now and not a single hairball. She goes crazy for the taste too.”
“We'd tried every paste and food. This is the first routine she actually enjoys — and it works.”

How We Stack Up Against What You've Already Tried.
Pastes, oils and hairball kibble all share the same problems.
Ask the vet
Why Cat Grass Beats Paste, According to a Vet.
We asked a feline veterinarian the questions cat parents ask us most.
Outdoor cats graze on grass, which helps swallowed hair move through. Indoor cats groom just as much but never get that grass, so hair sits in the stomach longer.
Yes. Grass is something cats seek out on their own, and lecithin has been used in hairball care for decades. Fed as directed on the label it's gentle and fits alongside regular food.
If your cat is vomiting repeatedly, not eating, lethargic or straining without producing anything, see your vet promptly. Treats support prevention; they don't treat an existing obstruction.
What Cat Parents Are Saying About Us.
Real results. Verified buyers. No filters.
“Two long-haired cats and I was cleaning up hairballs almost daily. Three weeks in and I can't remember the last one. They both think it's a treat.”
“Tried paste for years and he'd fight me every time. These he comes running for. The gagging at night has basically stopped.”
“I read the ingredient list twice because it seemed too simple. Cat grass, lecithin, salmon — and it works. Ordered the 3-pack.”

Most cat parents notice less gagging within the first week and fewer hairballs within two. Long-haired and senior cats can take a little longer — that's why the guarantee is 90 days.
For most cats, yes. Paste reacts after a hairball has formed; a daily cat-grass treat helps hair pass before it does. Many customers drop the paste entirely within a few weeks.
Yes — kittens in the 2–5 lb range get 5 treats a day. Introduce gradually alongside their normal food.
