Use Kangaroo Milk Replacer 0.4 for unfurred joeys, just prior to the onset of hair growth. Joeys at this age are prone to disease and mortality and should only be attempted by experienced carers.

Impact Colostrum Supplement may be fed to enhance the immune system.

Making up Milk

To make 100mL of milk: Mix 18g of powder (2½ scoops) with 90ml of warm water.

To make 1 litre of milk: Mix 180g of powder with 900ml of warm water.

Add about half the water to the powder first and mix to a paste. Then make up with remaining water and mix thoroughly. Water is preboiled to ensure that it is sterilised. If the water is too hot it can cause the milk to curdle. If it is too cold then it will be difficult to disperse the powder. An electric whisk can be used for mixing larger quantities. Milk can be stored in the fridge for a day or can be frozen for up to 2 weeks. It may be useful to store frozen milk in small portions (e.g. ice cube trays), so that the required daily feed volumes can be easily thawed out. Once thawed out, discard any unused milk, and wash feeding utensils thoroughly.

Feeding Guide

Warm milk to about 30°C and feed using a bottle and teat. A Wombaroo STM Teat is recommended for small in-pouch kangaroos and wallabies. Feed around 6-8 times per day for joeys with an Age Factor 0.4. If the joey is showing signs of dehydration (e.g. during hot weather), give extra drinks of water between feeds. Young joeys dehydrate rapidly if not maintained under optimum husbandry conditions. Consult your veterinarian or experienced carer for further information about husbandry and feeding of joeys.


Different species of macropods grow at different rates. Refer to the Wombaroo growth charts for guidelines for various species of kangaroos and wallabies. Weigh joeys regularly to verify weight gains and determine the volume of milk to feed. Overfeeding milk can cause diarrhoea so feed the suggested volumes in our tables.

Transitioning from Kangaroo 0.4 to Kangaroo 0.6 formula

Milk transition refers to when a joey is changed from one Wombaroo milk stage to the next. It is important to transition joeys at the correct age to ensure they are getting the proper nutrition for their stage of development. Note that transition is dependent on joey age and not weight, as underweight joeys still need to be transitioned at the correct time. Fur forms first on the bridge of the nose and head in developing joeys. When this occurs the young are ready to transition onto Kangaroo Milk Replacer 0.6 formula. Joeys are gradually transitioned over 10 days by mixing decreasing amounts of the 0.4 formula with increasing amounts of the 0.6 formula. This is outlined in the Wombaroo growth charts for various species.
