This charming trio of cats – Kit Kat, Archer, and Gandalf – all have unique personalities and needs. But the one constant? Their fur mom’s endless love for each of them. She makes sure that they each get the care they need while no kitty gets left out.
Let’s explore what makes each kitty unique and their natural NHV supplement routines!
Kit Kat has the most complex needs out of this feline trio. He has extensive dental problems (having had 8 teeth removed), heart arrhythmia, and early signs of cataracts in one of his eyes. These conditions can be a lot to deal with on their own, but to complicate things, Kit Kat also has Feline Immunodeficiency Virus (FIV).
As a condition that affects the immune system, FIV can make recovery from other conditions more difficult. Plus, there’s also a lot of stigma against FIV-positive cats. Many believe that they cannot lead a good life or that FIV is spread very easily amongst cats living together. However, this is not the case, and in fact, many cats with FIV can thrive! Kit Kat’s fur mom shares:

Since getting Kit Kat I’ve have such a soft spot for FIV+ kitties especially with the misunderstanding sometimes about the Illness
As a way to support this blue-eyed cutie, Kit-Kat takes a few natural cat supplements by NHV. Our supplements are 100% natural and vet-approved, and they only use human-grade ingredients so that you don’t have to worry about immune-compromised cats taking something artificial. Some of the supplements Kit-Kat takes include:
With his dental issues and other conditions, eating enough has been a concern for sweet Kit Kat. Since beginning his supplement routine, Kit Kat’s fur mom reports that he’s been eating more consistently! As they continue to navigate his wellness journey, they are considering additional NHV supplements, like NHV Turmeric, to further support his heart.
Although sweet Kit Kat has many health troubles, including ones that are poorly understood by other pet parents, we are so proud of Kit Kat’s fur mom for always staying on top of his health needs, never shying away from doing what’s best for him.
This black kitty is Archer. Compared to her other kitties, Archer is the healthiest of the three with few health concerns. But that doesn’t stop his loving fur mom from looking for ways to improve his health and wellness with natural cat supplements.
You see, Archer has some litter-box-related troubles due to his nub tail. His fur mom told us:

Since Archer has a nub tail sometimes his poo would get stuck on the outside of his booty the vet had told me that unfortunately that can happen with cats with nub tails and I added the pre and probiotic and I feel it has helped him. Poo is less often stuck on his booty
Sometimes when you’re dealing with difficult problems, you have to think outside the box – the litterbox! NHV Probiotic + Prebiotic is a blend of 7 strains of friendly bacteria that help to encourage digestive health. We add prebiotics, which are essentially probiotic bacteria’s food, to help feed the microbiota. When taken regularly, it may help cats experience better trips to the litter box, and like in Archer’s case, with less mess left behind.
Compared to Kit Kat’s concerns, Archer’s may seem like small-time stuff. But it’s amazing to see that Archer’s health and happiness can still be addressed through natural pet care in a busy household. It just goes to show that their fur mom has a big heart!
Finally, we have Gandalf. Gandalf was raised by his fur mom since he was just two days old! Now, many years later, he’s being saved again by his fur mom.
A couple years, Gandalf was recovering from bladder stone surgery. Bladder stones are an uncomfortable condition that can become quite serious if not addressed. While all three cats take NHV Tripsy and NHV Milk Thistle, Gandalf gets a bit extra due to his past concerns with his bladder stones! These two supplements are our top recommendations for naturally flushing the system and supporting your pet’s own detoxification processes.
Things have been going well for Gandalf, too:

Gandalf seems to have a little bit of a cold but he seems to be getting over it quicker than usual. I suspect it’s the supps and the [vitamins] he gets everyday and shower steams
And because he is part Siamese, this kitty also gets a little extra NHV OcuLove to help proactively address any potential eye issues down the line. You know what they say: an ounce of prevention is worth a pound of cure. For pet parents aware of potential future issues of their cat’s breed, this saying holds true!
If you have a multi-cat household and you’re balancing individual wellness needs and goals, it can definitely feel overwhelming at times. But we know that pet parents will do it anyway. Cats are special creatures. Funny, charming, curious, smart, and loving – they’re not just pets, they’re family, too!
While bigger families can seem more complicated, it comes down to having the right support. If you have a multi-cat or multi-pet household, our Pet Experts can help make personalized supplement suggestions for each of them. Simply use the chat button below to get started. We can’t wait to meet your fur kid!

Sometimes it can be tough to know what is bothering your four-legged friend because no two pets are alike! But a health issue that affects many of our feline and canine friends are bladder stones and urinary tract crystals. Stones are often triggered by an infection, but may also develop from kidney or liver disease, high blood calcium levels, improper diet, or genetics. Bladder stones tend to be smooth while crystals tend to be smaller and more jagged. So to help the body dissolve and flush calculi, Tripsy and Milk Thistle work together to strengthen the liver, help relieve inflammation, and promote urinary tract health.
To find out if your pet has urinary tract issues, have your vet run some tests like radiographs, CT scans, or ultrasounds to further investigate their symptoms and, from there, recommend an appropriate care plan.
Urinary crystals and stones can cause a lot of discomfort and stress for your furry friends. Ingredients like parsley piert, stone root, and gravel root have been used for centuries to support urinary tract health by encouraging the natural elimination of stones and helping to prevent urinary tract infections (UTIs). The diuretic and antimicrobial properties in Tripsy gently increase urine flow to keep things moving and help stop the formation of stones in the first place. Along with Tripsy's healing properties, Milk Thistle adds antioxidant support to help strengthen liver detoxification, encourage cell regeneration and soothe inflammation.
At NHV, we know that your furry friends are your family so we have made it our mission to provide the best natural supplements possible! Our master herbalist and holistic vet have created all of our formulations to be bioavailable and easy to administer in liquid form! For any questions about your furkiddo’s urinary tract health, our NHV Pet Experts are here to help!

Did you know your cat’s gut health is a key factor in their overall well-being? NHV Prebiotics + Probiotics for cats may be a valuable addition to your kitty’s regimen because it helps keep the GI tract healthy and, thus, contributes to your kitty’s overall health. The proprietary blend is designed and vet-formulated for your cat’s consumption. It contains 7 strains of human-grade probiotics, and each scoop has 5 Billion CFU (Colony Forming Units - amount of active good bacteria).
Addressing potential concerns before they become a problem is always a good idea. As pet parents, the wellness of our sweet furkids is of the highest importance. Even when they don’t have any current health concerns, it's natural for us to seek proactive measures to maintain their optimal health. NHV supplements, like our Probiotics + Prebiotics for cats, may just be what you need.
This formula, containing 7 shelf-stable, soil-based, spore-forming probiotics, helps keep your kitty’s digestive system in tip-top shape. The probiotic strains include Bacillus coagulans LBSC, Bacillus subtilis PLSSC, Bacillus clausii 088AE, Lactobacillus acidophilus 033AE, Lactobacillus plantarum 022AE, Lactobacillus casei 118AE, and Saccharomyces boulardii SBSC.
Probiotics are formed by “good” bacteria and are well-known for improving digestive and cat gut health. These natural ingredients also help other aspects of your pet’s body work well and restore balance.
The live microorganisms, like bacteria and yeast, in probiotics can potentially restore gut microbiota, the natural microorganisms in a healthy gut. These beneficial bacteria are crucial in supporting the digestive tract and addressing digestive problems (e.g., IBS, diarrhea, constipation). Our vet added 7 strains of probiotics (5 Billion CFU per scoop) to help optimize gut health in different ways.
Their ability to add good bacteria to the pet’s body may help improve the immune system. These bacteria act as a defense mechanism against pathogens, potentially preventing the onset of significant diseases.
When the gut is swollen, it can make your cat more anxious or stressed. This happens because there are lots of nerves connecting the gut and the brain. So, a healthy gut is important for a happy and calm kitty.
Unlike probiotics, prebiotics are carbohydrates that induce the growth of good bacteria.
Our probiotic formulation is expertly formulated and has added pumpkin and carrot powder to help enhance absorption.
At NHV, we care. From sourcing and manufacturing to delivering the final products to your doorstep, our team ensures everything is done with the highest quality. What does it mean? It means that our formulations are all backed by research. And none of them contains any artificial additives, preservatives, or coloring. They're GMP-certified full-spectrum extracts made in an FDA-registered facility.
You can read more about how we formulate our products here.
Don’t worry. Even if your kitty is a picky eater, administrating NHV supplements is fairly easy. Since it is liquid-based, you can add the dosage to their daily meal favorite treat or directly squirt it in their cheek pocket.
If you have any questions about our probiotics supplement, your kitty’s gut health, or anything else in the world of pet wellness, please don’t hesitate to reach out!
