A highly digestible formula for opossums weighing at least 45 grams until weaning. Fox Valley Opossum Formula is a rehabber-approved milk replacer that produces better weight gain, fewer digestive problems, and better acceptance than other formulas.

Fox Valley Opossum Formula mixes easily, smells wonderful, and there is no need to supplement the formula with any added cream, yogurt, or probiotics.

Fox Valley Formulas

Henry’s is proud to partner with Fox Valley Animal Nutrition, a leading manufacturer of formula milk for endangered and orphaned animals. Fox Valley uses only high-quality human-grade ingredients to create milk replacers that closely match the specific composition of the mother’s milk in order to assure proper nutrition and growth.

Mixing and Storage Guidelines:
Mix 1 part powder to 2 parts warm water. To determine the correct amount, see the guidelines below. Feed 3 to 5 times a day.  Gradually decrease both the quantity of milk formula and number of feedings per day as weaning approaches.

  • Add powder to warm water (approx. 100°F).
  • Blend until powder is dispersed in water.
  • Feed soon after mixing.
  • Mixing directions based on volume measurements, not weight.
  • Store any leftover formula in the fridge and feed within 24 hours.

Feeding Guidelines: Feed 1 ½  – 2 teaspoons per one ounce bodyweight daily, divided into 3 to 5 feedings.

For oral use only. These feeding directions are guidelines. As each animal is an individual, the feeding rate may be increased or decreased according to the needs of the neonate.

Made in the USA.

    Very good formula. I used this to rehab an abandoned baby that I found, and she did great and grew up big and strong with a proper weaning diet introduced and used with this product.
