    Life saver!

    Posted by Marie Nichols-Britt on 2nd Nov 2021

    This product has not helped kittens at the Clark County humane and that the Jeffersonville APA gain weight. I bought these products as a gift twice now when I saw we had some failing kittens and both groups report it back to me that this did help them. So I think it’s worth the investment.

    Recommend Ultraboost

    Posted by Becca Adams on 19th Apr 2021

    I've been using Fox Valley products for about a year now. Recently I took in an orphaned kitten that was a few days old. At a week of age, I thought she may be developing a blockage because of a lump I felt in her abdomen. Unfortunately, it turned out to be an enlarged non-functioning kidney. Because of this defect, she needed extra support so I began using Ultraboost instead of regular water. This was perfect since Pedialyte goes bad after 48-hours. Saved me a lot of time and money! Highly recommend.

    This is awesome have a really small baby squirrel was in such bad shape when I got her and she was not putting on much weight and loose skin all over I started her on the fox valley formula and ultra boost and she has filled out and growing and putting on weight. She is getting really energetic now too at 5 1/2 to 6 weeks old! She is so much fun to watch play!

    Saved my 18 year old cats life

    Posted by Jodi on 22nd Aug 2020

    My sweet 18 year old Lulu developed a bad infection that affected her nasal passages. Everything I tried to slowly syringe feed her made her gag. With one last attempt before I had to have her hospitalized with I feeding tube I tried this. I also purchased the miracle nipple/syringe and some bene-bac plus. She loves the ultra boost feedings, I don’t even have to hold her head. She’s slowly starting to put back on weight, has more energy and has perfect kidney function after her last set of labs. My vet is beyond impressed how well she is improving. Beyond grateful to see Lulu getting better thanks to these incredible products. Saved her life, Thank you!!!

    Switched from KMR + KMR 2nd Step

    Posted by Wendy Wolfe on 10th Jul 2020

    I originally ordered 1 bag of kitten formula and 1 bag of Ultraboost. After a couple feedings I immediately ordered a bunch more and several other products to have on hand. I added the probiotic because my little ones were on antibiotics but will continue adding it even when they're done with meds. I ordered the anti diarrhea product and the electrolyte replacer too. If all the other products are this good i want those on hand. Anyone who cares for kittens regularly knows diarrhea and dehydration happen occasionally and you want to remedy it as quickly as possible. I feel confident I have everything I need now. Since I switched to Fox Valley formula and Ultraboost I haven't had to deal with constipation, diarrhea., vomiting or bloating. I imagine I will get the occasional very sick kitten but no longer from formula issues.

    smells good and mixes easily with the formula. Replace 1/4 of the dried formula powder and mix with this. Use this in place of creamer.
