I bought this in an attempt to help with my cat’s allergies and runny nose. It helped somewhat however in the coldest weather it doesn’t seem to make a difference. At the beginning I did notice less of a runny nose discharge however long term use seems to not keep the same results.
VRS Health1 month agoThank you for sharing your experience. We’re glad to hear you noticed some initial improvement, though we understand how frustrating it can be when results aren’t consistent long term or during colder weather. We recommend checking in with your veterinarian to ensure the dosage is appropriate, as seasonal and weather changes can sometimes impact immune‑related symptoms. We appreciate your feedback.

I’ve been using this product on my elderly cat every night for several years now. She is still with us, I am positive it is due to this product.

When I 1st started getting this it was a very fine powder. However, recently I can see larger white chunks throughout. Apparently my cat can taste these and it very hard to get him to eat it all! Even when I’m mixing it with his favorite soft food. Wish this was back to the very fine and be consistent with that. It’s a very noticeable difference. Other than that he seems to do well on it.
VRS Health2 months agoThank you for sharing your feedback. We understand how a change in texture can make feeding more challenging. Because we use all‑natural ingredients, slight variations in color and texture can occur between lots. That said, we’ve shared your feedback with our product team, as consistency is important to us. We’re glad to hear your cat is otherwise doing well on the product and appreciate you taking the time to let us know.
