  1. Great product 5 Star Review

    Posted by on 14th Apr 2016

    This was my first time raising a squirrel. It had fallen from a tree and the mother abandoned it. Working under a licensed rehabber I was told to use this. I have had no problems and this little guy is very healthy and continues to grow.

    This is the best formula for 5+ weeks squirrels. My Red squirrel, LuLu, is transitioning from powered Esbilac to this product and she loves it and is having no issues with the transition. Thank you Leigh of Henry's for all of your advice and help!

  7. Gold Standard 5 Star Review

    Posted by on 26th Mar 2014

    This is the best formula for raising baby squirrels. I also use it to supplement my adult pet squirrel. It is easy to mix and use, and smells (and tastes) yummy. I recommend Fox Valley to anyone raising a baby mammal.

  8. Helped Save My Squirrel's Life 5 Star Review

    Posted by on 7th Mar 2014

    I've been caring for a baby that was abandoned after the nest tree was cut down, the siblings died, and the mama ran away. I estimate she was about a week old when we got her. For 5 days I fed her Esbilac, and it almost killed her. She wasn't gaining weight, she became weak, she basically looked like a tiny little skeleton...I felt terrible; she had been in better condition when she came into my possession. On the 4th day I ordered Fox Valley formula on a rush delivery, but still had to find something to feed her until it was delivered. I got Pro Biolac kitten milk replacer from my vet and it worked miracles (I'm including this bit in case someone needs something to feed a little one while they wait on FV), if I hadn't got the Pro Biolac, she would've died that night. There's no doubt in my mind. I finished out that small container and started FV a couple days ago. She absolutely loves it. She's gained more weight and her stools have become much more regular and normal on FV than they were on the kitten milk replacer.
    Would def. recommend it to someone raising a squirrel. :)

  9. Meets all the requirements 5 Star Review

    I have a very young squirrel, likely a nest fall, and he is doing fine with this product. The folks at Henry's are an excellent source of advice. All in all a great company.

  10. We've raised healthy, happy, playful squirrels on Day-One, both formulas. Love it! 5 Star Review

    Our squirrels are so healthy. We get them more dead than alive, and the Fox Valley Day One formulas are the best. They love it!!!!
