Helps your pet fight Feline Leukemia, FIV virus, other viral infections, and lymphoma
Nix the cat was given a heart-wrenching two weeks to live after being diagnosed with Feline Leukemia Virus (FeLV). But months later, Nix isn’t just surviving – he is still going strong. Discover the natural FeLV supplements that pet parent Cindy uses to support his journey and help him beat the odds.
In simple terms, FeLV (Feline Leukemia Virus) is a virus that weakens a cat’s immune system. It is a leading cause of cancer in felines, and it sadly has no cure.
You can think of it as a condition that makes it much harder for a cat’s body to protect itself from everyday germs and illnesses. FeLV leads to low appetite, significant weight loss, and loss of energy, like it had for poor Nix.
However, determined to help out her fur baby, Cindy looked for ways to help Nix feel better. That’s when she began using NHV natural pet supplements.
Getting involved in her fur kiddo’s wellness meant giving him two new supplements: NHV Felimm and NHV Multi Essentials each day.
NHV Felimm is a supplement for immune system support, particularly for pets dealing with viral infections like FeLV. In this vet-approved formula, herbs like St. John’s Wort, Aloe Vera, and more help to bring balance to the immune system. It’s a natural way to support cats with FeLV.
NHV Multi Essentials offers a mix of herbs and superfoods like alfalfa to give them a nutritive top-up of vitamins and minerals while encouraging healthy digestion. It’s great for cats with FeLV, which affects appetite.
So, how did the new routine go? Well, Nix has officially passed the two-week mark – months ago! And he’s still going strong. Cindy shares more about his improvement:

Nix has been taking Felimm, and when he was first diagnosed with FeLV the vet said he likely had about two weeks. It’s now been a month, and I truly believe your product has helped. We have also seen an increase in his energy, sleeps a bit less, and is eating a ton
How awesome is that? We couldn’t be happier for Cindy and Nix as they get more quality time together. It truly warms our hearts to know sweet Nix is feeling more like himself, because we understand how tough this condition can be.
As a part of a multi-cat household, managing FeLV can be tricky. That’s why Cindy gives Nix’s sister, Amber, NHV Multi Essentials as a proactive support:

Nix and Amber have been loving the Multi Essientials. Nix is doing great still which is amazing. We can’t thank you guys enough and for your products.

Whenever our pets get sick or something is off, it takes a toll on their immune system. Give your furkiddo a little extra support with NHV’s Immune System Support Gold to bolster their natural defenses.
All living creatures are susceptible to harmful microorganisms invading their body and making them sick. Your cat or dog’s first line of defense is their skin - a physical barrier protecting them from the outside world. Beyond the skin, vertebrate animals (like humans and your pets) have also developed a complex system to target and fight off diseases called the immune system. So, in other words, the immune system is your furkiddo’s best defense against pathogens and infectious diseases. The main parts of the immune system are:
From the moment they open their eyes, our furry friends want to explore, sniff and play. Sadly, many of our four-legged friends will experience some form of illness in their lifetime, which will weaken their immune system and make them susceptible to all sorts of other health complications. Our Immune System Support Gold can be used for proactive pet care as well as be helpful for more severe conditions, like a degenerative disease where their immune system may be severely weakened. NHV supplements are formulated to be used alongside conventional veterinary treatments as they contain many beneficial properties to support your pet's overall vitality as well as add extra support to help restore healthy immune function.
Any time your furkiddo's health is off track, their immune system is most likely affected. NHV's Immune Health Kit contains BK-Detox, ES-Clear, and Turmeric. BK-Detox helps flush the lymphatic system of toxic waste (especially areas of the body having scar tissue or swelling), support gentle detoxification of vital organs, and help to build new blood cells. Although NHV ES Clear is our leading degenerative disease support supplement, ingredients like Sheep's Sorrel and Slippery Elm are also highly beneficial for their nutritional qualities and for boosting white blood cell and T-cell production. Turmeric adds extra antioxidant support to enhance the body’s immune response and soothes inflammation.
With NHV Supplements, you can help provide your furry friend with the extra support they need to restore their immune health and support other vital body processes. All of our care products are created with 100% organic and wildcrafted ingredients. If you have any questions about your pet’s unique health needs, Get in touch with an NHV Pet Expert - we’re always happy to help.
Made with the finest, organically grown, or ethically harvested herbs. Made specifically for pets, vet-formulated and vet approved.

The health benefits of multivitamins aren’t just for humans. Cats have many of the same nutrient needs as we do, and some need even more than others depending on their age and health.
A multivitamin supplies the vital nutrients your kitty needs to be healthy and to fight off potential health problems. Dr. Cook, DVM, CVA in her blog states that vitamins “help to regulate the body processes, protect the body from environmental toxins, and break down nutrients such as carbohydrates, proteins, and fats so the body can utilize them”.
The best way to give your cat vitamins and minerals are from whole food sources and not just isolated synthetic vitamins. NHV Multi Essentials contains a powerful blend of alfalfa, oat, dandelion, kelp, parsley, marshmallow, chickweed, stinging nettle, Asian ginseng, yucca and Oregon grape.
Health Benefits of NHV’s Multi-Essentials for Cats
