Review: fox valley saved my squirrel - about a month ago, some strange circumstances landed a less than week old baby squirrel in my care (first pic is from the night i got her) i was feeding her a generic brand of puppy formula as that was all that was available at the time. flash forward to about a week or two later, it became apparent that she had become emaciated and was battling aspiration pneumonia (which went away with antibiotics). admittedly this was partially due to my lack of knowledge and experience as i had never raised one so young on my own. but i digress. i immediately ordered fox valley ultraboost, electro stat and 32/40 formula. within days she began gaining weight and her ribs became less visible. in less than a week she had gone from dangerously underweight to growing hair and on the low side of the average weight for her age. i wholly credit her recovery to fox valley’s ultraboost and formula, and now at five weeks she’s on a combination of the 32/40 and 25/50 formulas. (progress pics included!!) i will warn that when switching from puppy formula to fox valley her stools changed from a golden brown to a light yellow and became harder so stimulating might take a little longer. a little constipation did occur at first but nothing a little electrolytes didn’t fix. but overall fox valley’s products have been nothing short of amazing and she seems to love the taste as well! Review: Great Additive - I bought this to add to my kittebs who were not thriving as I thought they should be. This has added more nutrition and they are doing great. I'm glad I tried it & it will be regular staple in my Rescue Supplies. ## Features - High Fat Nutritional Formula: Specially designed high fat formula provides essential nutrition for all wildlife species - Versatile Nutrition Booster: Add to Esbilac or other formulas to increase nutritional content and caloric density - Emergency Formula Solution: Add to skimmed milk powder to create a temporary formula for emergency feeding situations - Quality Manufacturing: Manufactured in the USA to ensure premium quality standards and safety - Convenient Package Size: Each bag contains 0.5kg powder milk replacement part for easy storage and use - Enhanced Digestibility: Fortified with essential vitamins and minerals while maintaining digestibility for young animals - Multi-Species Application: Recommended for orphaned squirrels, flyers, rats, mice, Eastern cottontails, opossums, kittens, and puppies ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N9HW6N0 | | Additional Features | Easy to Use, Natural Product, Veterinary Approved | | Age Range (Description) | Baby | | Age Range Description | Baby | | Animal Food Diet Type | Veterinary Diet | | Best Sellers Rank | #139,949 in Pet Supplies ( See Top 100 in Pet Supplies ) #353 in Small Animal Health Supplies #52,351 in Sports Fan Shop | | Brand | Henry's | | Brand Name | Henry's | | Breed Recommendation | Any Breed Size | | Customer Reviews | 4.7 out of 5 stars 169 Reviews | | Dog Breed Size | All | | Flavor | Vanilla | | Item Form | Powder | | Item Weight | 16 ounces | | Manufacturer | Fox Valley Animal Nutrition | | Number of Items | 1 | | Occasion | Birthday | | Pet Type | Small Animal | | Product Benefits | Boosts weight gain with enhanced digestibility and added nutrients | | Recommended Uses For Product | weight gain for baby animals, emergency formula for wildlife | | Special Ingredients | Dried cream, whey protein isolate, vitamins, minerals | | Specific Uses For Product | weight gain for baby animals | | Target Species | Squirrel | | Unit Count | 16 Ounce | ## Product Details - **Age Range (Description):** Baby - **Brand:** Henry's - **Flavor:** Vanilla - **Item Form:** Powder - **Specific Uses For Product:** weight gain for baby animals ## Images ![Fox Valley Day ONE Ultraboost Formula for All Animals, 1 lb. - Image 1](https://m.media-amazon.com/images/I/61BY8a9JrXS.jpg) ![Fox Valley Day ONE Ultraboost Formula for All Animals, 1 lb. - Image 2](https://m.media-amazon.com/images/I/61-lTr1WC4S.jpg) ## Questions & Answers **Q: Is it appropriate for a 3 week old raccoon?** A: When I Google it, it says it's appropriate for squirrels rabbits and opossums... It wouldn't hurt a raccoon, I don't believe, but I've never tried to care for a baby raccoon. I also got several suggestions for kitten and puppy food, which I know you can feed grown raccoons. But, I don't know what they can handle at 3 weeks. **Q: Is this ok for older squirrels still drinking formula?** A: Yes it is! However, note that it contains extra fat and other nutrients, so it is best for a squirrel that needs to gain weight. Otherwise, it is better to use Fox Valley 20/50 for older squirrels still drinking formula. **Q: What product is best for Opossums** A: You can use Fox Valley 32/40 for opossums. Fox Valley Nutrition also sells a more specific formula for opossums: https://store.foxvalleynutrition.com/day-one-2530 ## Customer Reviews ### ⭐⭐⭐⭐⭐ fox valley saved my squirrel *by K***M on May 28, 2024* about a month ago, some strange circumstances landed a less than week old baby squirrel in my care (first pic is from the night i got her) i was feeding her a generic brand of puppy formula as that was all that was available at the time. flash forward to about a week or two later, it became apparent that she had become emaciated and was battling aspiration pneumonia (which went away with antibiotics). admittedly this was partially due to my lack of knowledge and experience as i had never raised one so young on my own. but i digress. i immediately ordered fox valley ultraboost, electro stat and 32/40 formula. within days she began gaining weight and her ribs became less visible. in less than a week she had gone from dangerously underweight to growing hair and on the low side of the average weight for her age. i wholly credit her recovery to fox valley’s ultraboost and formula, and now at five weeks she’s on a combination of the 32/40 and 25/50 formulas.
