Feeding Instructions for Baby Animal Milk Replacer

Before feeding, make sure to follow our Mixing Instructions for Milk Replacer Formula.

Exotic Nutrition offers Marsupial Milk Replacer (for sugar gliders and opossums) or ZooPro Milk Replacer 32/40 (for other mammals). These powdered milk replacement formulas are a complete food source for orphaned or rejected baby animals. They are easily digestible, highly palatable, and made in the USA.

Feeding Instructions for Milk Replacer Formula

It is crucial to let the baby eat at its own pace, especially if it is not willingly suckling from the syringe. Rapidly squirting the liquid can lead to aspiration, which can cause the liquid to enter the lungs and potentially suffocate the baby.

After feeding, it is important to stimulate the baby to allow it to defecate and urinate. You can use a moist cotton ball to gently stimulate the genital area until the baby stops eliminating waste.

Keep the baby animal warm in a Calming Glove or fleece bonding pouch next to your body. Alternatively, you can place a Pet Warming Pad in a glass aquarium or plastic storage container, away from the baby. Cover the heating pad with a soft towel and monitor the temperature, ensuring it remains stable at around 100°F near the baby.

The amount to feed depends on the joey's OOP (Out of Pouch) age:

  • 1 week OOP (10–20g): 0.5 ml every 2 hours
  • 2 weeks OOP (14–24g): 0.5 ml every 2 hours
  • 3 weeks OOP (15–25g): 1 ml every 4 hours
  • 4 weeks OOP (21–32g): 1 ml every 4 hours
  • 5 weeks OOP (28–39g): 2 ml every 4 hours
  • 6 weeks OOP (33–44g): 2 ml every 4 hours
  • 7 weeks OOP (38–49g): 3 ml every 4 hours
  • 8 weeks OOP (43–59g): 3 ml every 4 hours
  • After 8 weeks: Offer 4 ml every 4 hours until the glider begins eating solid foods and reaches adulthood (approximately 85–139g).

Baby Squirrels

Age Weight of Baby Schedule Amount per Feeding Night Feeding
0–1 Week 10–20 grams Every 2–3 hours 0.5 cc Feed once per night
1–2 Weeks 20–40 grams Every 2–3 hours 0.75–1 cc Feed once per night
2–3 Weeks 40–60 grams Every 3 hours 2–3 cc Before bed
3–4 Weeks 60–80 grams Every 3–4 hours 3–4 cc Before bed
4–5 Weeks 80–120 grams Every 4 hours 4–6 cc Before bed
5–8 Weeks 120–240 grams Every 4–6 hours 8–12 cc Before bed
8–10 Weeks 240–400 grams 1–2 times per day 12–20 cc Solid foods at night
10–12 Weeks 400–600 grams 1 time per day Wean with solid foods at night

If you are unsure about your baby squirrel's age, you can use the following formula to determine how much ZooPro Milk Replacer 32/40 to offer: Offer up to 5% of the squirrel's body weight per feeding. For example, if your squirrel weighs 100 grams, offer 5 ml of milk replacer per feeding. If your squirrel weighs 50 grams, offer 2.5 ml per feeding.

Baby Rabbits

The following amounts should be divided into two feedings per day:

  • Newborn to 1 week: 4–5 cc of formula
  • 1–2 weeks: 10–15 cc of formula
  • 2–3 weeks: 15–30 cc of formula
  • 3–6 weeks (until weaned): 30 cc of formula

Until their eyes open (around 10 days), after each feeding, it is important to stimulate the baby rabbit to defecate and urinate. Gently stroke the genital area with a soft cloth or moist cotton ball to replicate the behavior of the mother rabbit, who would lick her young to stimulate them to eliminate waste. The stool may be soft and vary in shades of green and yellow.

Baby Opossums

Weight of Baby Amount Frequency
30 g 1.5 ml Every 2–3 hours
35 g 1.75 ml Every 2–3 hours
40 g 2 ml Every 4 hours
45 g 2.25 ml Every 4 hours

Baby Skunks

Mix 1 part powder with 2 parts hot water (approximately 115–120°F).

Feed 1 to 1.5 tablespoons (15–22 ml) per ounce of body weight daily, divided into 4 to 6 feedings.

Baby Raccoons

Mix 1 part powder with 2 parts hot water (approximately 115–120°F).

Feed 2–3 tablespoons (30–45 ml) per 4 ounces of body weight daily, divided into 4 to 6 feedings.

Storage Instructions

It is recommended to prepare fresh milk replacer for each feeding whenever possible. Prepared milk replacer can be stored in the refrigerator for up to 24 hours. Store the unmixed powder in a cool, dark place until the best-by date.
