About This Product:

  • Wombaroo Cat Milk Replacer is a highly digestible, easily prepared milk substitute formulated to closely resemble the nutrient composition of queen milk. It contains acceptable levels of taurine and arachidonic acid, nutrients that are essential for growing cats.

  • Use Wombaroo Cat Milk Replacer for hand-rearing orphaned kittens or supplementing queens with large litters.

  • Wombaroo Cat Milk Replacer is a powder and is available in a 215g pack which makes 1 liter. It also comes in packs of 1kg, 5kg, 10kg and 20kg.

Directions for Use:

  • When unopened, the powder remains stable for up to 18 months if stored below 30º C (86º F) and protected from moisture.

  • To make one liter of milk, add 215g of powder to 300ml of pre-boiled warm water. Mix into a paste, then make up to one liter using pre-boiled warm water and mixing thoroughly. An electric whisk can be used for mixing.

  • Prepared milk can be stored for 24 hours if refrigerated, or up to two weeks if frozen.

  • Milk that has been thawed should be mixed well before use. Do not refreeze.


  • Success in hand-rearing kittens greatly improves if they receive colostrum at birth. Impact Colostrum Supplement is available for kittens that did NOT get colostrum from the queen.

  • Keep kittens in a clean, draught-free environment at about 30º C (86º F).

  • Warm Wombaroo Cat Milk Replacer to about 35º C (95º F).

  • Feed from a bottle with teat every 2 hours for the first three days, reducing this to every 4 hours by the end of the first week. Stimulate kittens to defecate and urinate after each feed.

  • During the second week, reduce feeding to six hour intervals. Encourage kittens to lap once their eyes open and voluntary bowel movements begin.

  • To avoid dehydration during periods of hot weather, give kittens a drink of pre-boiled water between feeds.

  • Always offer kittens drinking water once their eyes open and they become mobile.

  • Consult your veterinarian or breeder for particular advice about caring for your breed of kitten.


  • Kitten body weight should increase by 10 to 15g per day. Weigh kittens regularly to verify weight gains and to determine milk feed volume.

  • Overfeeding milk can cause diarrhea, so feed the suggested volumes in our tables.


  • When kittens are about four weeks old, they should show interest in solid food. To entice them to eat solids, offer a small portion of specially formulated dry kitten food soaked in Wombaroo Cat Milk Replacer.

  • Once kittens start to eat solid food, continue to increase the solids and reduce the milk in their diet until they are fully weaned at about eight weeks.

  • Consult your veterinarian for more advice.


  • Wombaroo Cat Milk Replacer not only provides the best nutrition for your kittens, it is also inexpensive to use -- only a few cents per day.
