Daily Cat Dental Powder
It all starts in the gut
Digestion, coat, skin, energy, immunity. They’re all connected to your cat’s gut. When that balance is off, the symptoms show up everywhere. Happer™ delivers clinically studied probiotic strains that help restore gut balance, so their body can do what it’s supposed to do.
"It’s like getting your cat back."
That’s what owners keep telling us. Not overnight, but within weeks, the small changes start adding up. More energy. More appetite. More of the cat you remember.
Dr. Heather Lindqvist, DVM
Double Board-Certified Feline Medicine Specialist
"When a cat isn’t acting like themselves, the gut is the first place I look. Whether it’s runny stools, a dull coat, or just sleeping all day - 9 times out of 10, that’s where the root cause hides. Happer™ gets the formulation right, it’s tasteless so cats actually take it, and that daily consistency is what makes the difference."

My cat threw up at least once a week for 3 years. I just thought that was normal?? Started adding Happer to her food about a month ago and I honestly can’t remember the last time I cleaned puke off the floor. Should have tried this sooner...

My girl was hiding under the bed all day pulling her fur out. Barely came out to eat. I don’t know what I expected from a probiotic honestly but she’s back on the couch with us every night now. Her fur is actually growing back too.

If your kitten has gas that clears the entire room just buy this. Im not even exaggerating my boyfriend was googling if we could return a cat. We tried 2 different foods first and nothing touched it. Two weeks on this and the smell is basically gone.

Took her to 3 different vets for the scratching. Over $600 in bloodwork and skin tests and not one of them could figure out what was wrong. Nobody had answers. A $35 probiotic did what none of them could and I still dont fully understand how but it worked

Month 2 update and stools are still firm. You guys dont understand I went through like 6 or 7 different foods over the past year thinking it was a food problem. Spent so much money on premium grain free organic whatever. It wasnt the food. It was her gut the whole time

Caught my 17 year old batting around a hair tie on the kitchen floor yesterday. Hes 17. He stopped playing months ago and honestly just slept all day every day. I thought we were in the final stretch with him. I guess he wasnt ready to give up yet.

My cat licked her belly completely bald after her spay. Like smooth skin, no fur at all. Vet said stress and to just wait it out. Waited 4 months and nothing changed. This is the first thing thats actually made fur come back. Its not fully grown in yet but its growing and thats huge for us

Im the guy whos thrown money at every single cat product that promised results. Powders, different foods, expensive vet visits, all of it. Was fully expecting this to be another waste. My cats diarrhea cleared up in about 2 weeks and has stayed that way. Kinda mad I didnt try this first.

I live in a studio apartment and my cats litter box was making the whole place smell horrible. Like I stopped having friends over because of it. Couldnt open the door without it hitting you. Everything firmed up and the smell is honestly like 80% better now. Sounds dramatic but it works really well.

When they told me early kidney disease I just sat in my car and cried. I was honestly preparing myself for the worst. Her last blood panel came back better than the one before it and my vet actually said whatever youre doing keep doing it. Shes eating again and has energy again. Im not getting my hopes up but yeah this is helping.

Frequently Asked Questions
Find answers to our most commonly asked questions
How long does it take to see results?
+
Every cat is different. Some owners notice changes within the first 1-2 weeks, but most see real improvements around weeks 3-4. That’s why our guarantee covers a full 60 days.
Will my cat actually take it?
+
Happer™ is completely tasteless. Just add drops to their food (wet or dry), and they eat it like any normal meal.
Is it safe for kittens and senior cats?
+
Yes. Happer™ is safe for cats of all ages, breeds, and sizes, whether they’re 6 months or 16 years old.
Can I use it alongside my cat’s current medication?
+
Happer™ is a supplement, not a medication, and works safely alongside most treatments. If your cat is on something specific, check with your vet first.
How do I give it to my cat?
+
Check the dosage guide on the bottle for your cat’s weight. Add the drops to their food, mix lightly, done. They won’t taste a thing.
What happens if I stop using it?
+
Probiotics work best with daily use. If you stop, gut bacteria can gradually shift back over time. Most owners keep Happer™ as part of their cat’s daily routine.
What if it doesn’t work for my cat?
+
Send it back within 60 days for a full refund. No questions asked.
