When I adopted Mr. Mushu, he was 8 yo with allergies. So his diet is limited to chicken and turkey. His skin and stomach are sensitive to many other foods. He also has respiratory illness where he would sneeze multiple times at once. Well he has never had any allergic reaction to the Immuno 5. He doesn't take any other supplements or drugs. So I'm very thankful his respiratory system is benefiting from the Immuno 5. I mix it with his favorite squeeze up snack.

I’m with a cat rescue and have anywhere from 1-6 cats/kittens in my care at any given time. These cats come to us from different situations and at varying ages, so preventing and boosting their immune response is key. Every cat gets this every morning— (kittens only a 1/4 to 1/2 dose) mixed in with their wet food and since my first purchase about 2 years ago, it’s cut down upper respiratory infections by almost 100% and it’s been such a relief. The cats seem to love the taste too- no turned noses here!! Thank you so much for this amazing product.

My cat loves it and it's helping with his sinuses - not sneezing near as much. The CRS C/S team is fantastic to work with. They exemplify what customer service SHOULD mean? :)

- JHJody H.Verified Buyer2 months agoReviewingimmuno-5®Rated 5 out of 5 starsWorks great!
I love this product as has greatly supported my cat's immune health. He has HCM and is prone to URIs. This has definitely helped reduce those infections, and duration when he was diagnosed. It works great as an everyday supplement for him, and my other kitties as I administer to all.
