To be taken twice daily. Determine your pet’s weight and then use the easy chart below to determine the correct dose. This is the minimum dosage.


Pet's Weight Dosage

0 - 15 lb = 0.5 ml

16 - 30 lb = 1.0 ml

31 - 45 lb = 1.5 ml

46 - 60 lb = 2.0 ml

61 - 75 lb = 2.5 ml

Over 75 lb = 3.0 ml

For small animals (rabbits, ferrets), avians and reptiles use 1 drop for every 2 lb of body weight.

How to Administer
Shake well before use. The easiest method is to use the dropper provided and place the drops into your pet’s food or favorite treat. You can also use the dropper and squirt directly into the pet’s mouth. Some pets can be finicky, if this occurs consider hiding the drops in foods most pet’s love such as fish, chicken or yogurt or a favourite treat. If your pet only eats dry food then soak a few kibbles at feeding time.

For Best Results
Herbal dietary supplements are beneficial to the health and well-being of your pet and are safe for long-term use.

Supplements generally take two to four weeks to take effect, however this will vary from one animal to the next.

Our beautiful cat Bell was diagnosed with a mass in her small intestine. Her blood work panel was normal in all aspects. Her only symptom was that she had lost significant amount of weight from 8 lbs to 5.3 lbs between May 2017 and Nov 2017. During that time she she ate normal amount of food ( Wellness dry maintence food about 1 cup and 1/8 can of their wet food . Her behavior stayed the same and poops and pees the same. So after several trips to the vet and ultrasound we were told it was a mass and that they believed it was either a lymphoma mass or a carcinoma mass. Outlook was not good. On the bright side she was able to eat, keep her food down and poop. Of course we were devastated with the news. Another beloved pet sick with what they believe is cancer.( death sentence) My friend Sandi ‘s cat had recently passed at a very young age of some form of aggressive cancer.. she is the one who gave me her remedies from Nhv she was unable to save her fur baby . Sandi believed that her cat had been diagnosed to late and the cancer to aggressive for the remedies to work. However she had researched NHV And believed that the remedies would work had she had the luxury of time. Sandi upon hearing about Bell offered to give me the her remedies in hopes of helping my cat Bell. I checked out the website chatted with NHV staff on line asking additional questions based on my cats condition as to what products they felt would be most beneficial. They were very helpful in their recommendations. My cat is maintaining her weight between 5/34-6lbs as it appears she is not losing more weight as of January 25 2018. Bell was only slightly above 5 lbs when originally seen at vet back in November 2017. I began by removing all dry food from my cats diet : feeding only the following : 2x per day approx total 1/2 can as my cat was never a big eater. Beef and chicken liver ground into a pate Distilled water, fine ground kelp. Omega 3 salmon oil, nu-feline grass powder, cbd oil 6 drops. Nhv products 10 drops of turmeric 10 drops es-clear 10-drops bk-detox 12-drops Felimm 12-drops milk thistle 12-drops nature’s immune for cats *note with all Nhv products I followed the recommended amt of drops per pound for 2 months . I gradually increased the dosages up to what is shown above . ( based on no ill signs) Actual weight of my cat is 5 3/4 to 6 lbs. Also l make the liver pate separately and add all other ingredients to each serving. ( to keep it fresh). I am very pleased with the combination of remedies and we will be going back to the vet in May for another ultrasound to see if there were any changes in her blood work, see if tumor is the same size/or changed ( hopefully smaller) . We are staying optimistic and Bell has shown no sign of pain or discomfort during this entire time and is acting her normal self. *

Using Felimm and BK-Detox have totally changed our two sickly kittens! They are finally gaining weight, and their fur is growing full and shiny after being thin and patchy for months. It's been an amazing transformation to watch. I just ordered a respiratory formula for another kitten--I'm very hopeful and excited to see the results. Furthermore, the customer service is excellent. They sent me the wrong product the first time that I ordered, and they remedied the situation quickly and easily. I absolutely recommend NHV! *

My cat Mosey has been on this for 6 months. He was diagnosed with FIV and was very sick. I thought I needed to put him asleep but couldn't. He was only 5 yrs young. I prayed and was led to look up this illness to learn more about it. That's when I discovered FeLimm and the reviews were great. He improved almost immediately. I give it to him 3 times a week. He's gained his weight back plus, He's active, eating well. My vet was shocked. She was amazed and said she would let her colleagues know about this. I'm thankful for FeLimm! *

Emma - New York | July 24, 2017

I've really seen a great difference in my cat's fur and health after using FELIMM for four months. He is FIV positive, and was a shelter cat rescued from the streets, so his fur wasn't as healthy as it could be. After giving him FELIMM twice a day with his wet food, his fur is healthy, his sniffles have mostly cleared up, and he has an overall happy and healthy demeanor. I will definitely continue to use this product. *

My cat with diagnosis of FIV responded quickly to this and his condition improved almost overnight. I thought I was goning to lose him. He's gained weight, eating now, which he had stopped eating almost altogether and acting like his old self. Thank God I found this after much prayer. *

Linette - Singapore | September 23, 2016

My cat started having bouts of vomiting in December 2015. The vomiting increased in frequency and in February 2016, she started throwing up blood. During these months, she was going to the vet regularly and taking medication. However, the vomiting got worse over time. In May 2016, she went for an endoscopy. The photos revealed her stomach walls were severely inflamed and bleeding. There was also a tumour blocking her stomach exit. Biopsy results confirmed she had large cell lymphoma (B-cell). Blood tests on that day showed she had FeLV and FIV. Shortly after that, I started giving her ES Clear and Felimm. At this point, she was not taking any medication. Her vomiting gradually happened less often and also had less blood. By July 2016, the vomiting had stopped. Another blood test revealed that she was no longer bleeding internally. Although there were no tests done to confirm whether the stomach tumour was still present, the fact that food was passing out from her stomach normally led us to believe the tumour had either shrunk or wasn't present anymore. Throughout all this time, the NHV staff were very helpful and gave useful advice when I contacted them. My sincerest thanks to them for making a product that helped my cat immensely. *

Karen - Livonia, MI | August 8, 2016

Thank you!!! I have a 10 year old FIV positive cat that I tried the FELlMM on for the first time about 2 month ago. He is doing so much better now. We have a total of 8 adult cats that we rescued because they were unadoptable. All with different issues. We try to make their lives as comfortable and enjoyable as possible. Can't wait to try the other products. Thank you. *

Hi folks at NHV! Bayou 2 1/2 year old male cat, has been plagued with chronic sinusitis since a kitten. Brave boy has learned to breathe partially through his mouth. It makes his breathing often very noisy: I call him Jacob on “bad days”, referring to the sound of a truck’s Jacob brake; you get the picture… He also has mysterious food allergies (he’s itchy), and regularly gets intense larynx spasms. Having studied in animal natural care, I’ve tried everything under the sun, (including homeopathy) at least to keep him off antibiotics or [**pharmaceutical name removed]. No miracle there. This was until I started to seriously implement your products in his daily routine: he’s been on ES Clear, Felimm and Resp-Aid (a system cleanser, immune booster and sinus help) for a little over 2 weeks now. On the second day, my husband was very worried that Bayou had not slept with us on the bed that night, because we barely heard him!! Today his nose is not as stuffed, his “headachy” days seem to be over. He’s not completely out of the woods yet (I had to start slowly with Resp-Aid, because his spasms were worse at first) and he has mucus coming out of his worst nostril, but frankly, other brands/plant combinations or medications would completely dry up and deeply jam his nostrils, and THAT was bad, which is not the case with NHV products. Also, he doesn’t have as severe episodes of scratching his tail and paws; His larynx spasms are sparse, and as a bonus,he’s not prone to as much anxiety. I’ve witnessed a couple of days where I heard him gently honk like a donkey over an object. To my surprise: OMG! would Bayou be recovering his sense of smell?! I know I will have to keep treating him for a while, or forever, and I’m not sure if he can completely recover from this condition, but I sure appreciate seeing him enjoying his cat life more! Thank you! *

Eddie - Illinois | May 16, 2013

Eddie is our 8 year old cat was having different health upon a vet examination and lab test we were told that he had FIV. I spent sometime doing some research and found out that it would help to boost his immune system. I then found Felimm and Eddie has been on it for months. The bad breath and diarrhea are gone. He is much happier and more frisky and I known that product has helped him. Will continue to use it. *
