    The absolute best squirrel formula

    Posted by Elicia Ross on 15th Oct 2021

    I tried another brand of formula before trying FV and my baby did not do well on it. He had constant diarrhea and had troubles gaining weight. Tried the homemade goats milk version and he did well on it for a little while until he became constipated. Once I found Fox Valley 20/50 he did amazing. Consistent weight gain, perfect bowels, lots of energy, it mixes well, and he loves it! I truly appreciate the affordable pricing and fast shipping that Henry's provides!

    This is the perfect formula for squirrels over 4 weeks old. It mixes smoothly, smells wonderful and my babies love it. They have gained weight and have become extremely active due to drinking this great formula. Thank you for caring for the nutrition, safety and comfort for the animals in all of your products.

    FOX VALLEY 20/50

    Posted by Samii Taylor on 5th Aug 2021

    I appreciate the fact that 20/50 is convenient and supplies the nutritional needs of my rescue squirrels. However, I'm not in love with the new formula. Not sure what changed, but it's not the same as in 2019. I have to watch carefully for bloat on the younger squirrels. Once they are 5 wks old, this does not seem to be a problem. This is still my go-to for keeping my rescues healthy.

    Best Option for Baby Squirrels

    Posted by Anne on 15th Jun 2021

    This is the best and really only option to consider for nursing baby squirrels. I've weaned little ones from homemade goatmilk formula to this with great success that go on to be released. Make sure to read all of the great information on baby squirrel care and feeding that is on the site because it's super helpful for those with little and no experience.
