Helps your pet fight Feline Leukemia, FIV virus, other viral infections, and lymphoma
Say hello to Sweetener! This kitty has a massive following – and we’re fans of him at NHV, too.
Sweetener was born with eye troubles and he is FIV positive. As a result, he might not look like most cats. But over 100,000 people have fallen in love with his sweet, funny, and dramatic personality!
Because of his unique health needs, his furmily uses a natural routine to help him feel his best. Let’s take a look at the NHV supplements Sweetener takes to keep his immune system strong despite being FIV positive.
Sweetener was found on the street as a young kitten in cardboard box. Sadly, most of his siblings didn’t make it. But his fur mom found him and rushed him to the vet, where she was told that he might not survive the night.
Thanks to her love, Sweetener survived.

Sweetener now lives his best cat life, loved and adored by his mom and his thousands of fans. But Sweetener does still experience challenges. As a partially blind kitty with FIV (Feline Immunodeficiency Virus), Sweetener will have flare-ups of immune system issues, like chronic infections, weight loss, and inflammation.
One day, Sweetener wasn’t feeling too hot. His pet parent shares:
He suddenly lost his appetite and started losing a lot of weight. My little boy who usually loves food didn’t even want to eat anymore. As a cat parent, that feeling is honestly terrifying. I posted a story asking if anyone had advice because I just wanted my baby to feel better
When we saw Sweetener’s story, we were instantly reminded of the many FIV+ cats who have been supported by our supplements in the past. That’s when we reached out to offer a new, holistic care plan.
Our suggestions for Sweetener included NVH Felimm, NHV Yucca, and NHV Stimmune.
Like all NHV supplements, they’re 100% natural and vet-approved, so no pet parent has to worry about anything artificial affecting their kitty’s system – a huge concern for pawrents whose little ones have immune system troubles, like FIV in cats!

Since Sweetener started using NHV Yucca, Felimm, and Stimmune, his appetite and energy have improved noticeably. Having gentle and proactive options like these makes a real difference in helping Sweetener stay happy and active.
Even Sweetener’s pawrent is impressed with how his low appetite rebounded:
It’s been about 2 weeks now of giving him the drops every day and I’m so happy to say… Sweetener is eating again! Not only eating… but now he’s eating twice his portion a day. Seeing him enjoy his food again makes me so relieved.
Recently, Sweetener is experiencing a new challenge, familiar to many kitties: anxiety in cats. It can be especially common in cats with vision issues. That’s why we recommended NHV Matricalm to go along with his other supplements.

NHV Matricalm is a gentle, non-habit forming supplement for pets experiencing stress, anxiety, and even separation issues. It has herbs that have been traditionally used for reducing stress in pets, like chamomile and passionflower.
Armed with this new supplement, sweet Sweetener is nor getting holistic care for every concern! And there is no worry mixing and matching supplements from the NHV range; they were designed to be used safely together!
Although Sweetener had a tough beginning in life, it only took some love to see a dramatic change. This sweet boy, who loves cuddles and making biscuits, is proof that every cat can thrive.
NHV makes natural supplements for so many different conditions in cats and honestly… they really helped my boy.
