This homemade kitten formula recipe is approved by veterinary nutritional experts, and so will be the best option until you can find some commercial formula.
15gLow-fat curd (The curd must NOT be cottage cheese, as this may clot in the kitten’s stomach)
8gLean beef hash
3gEgg yolk
3gVegetable oil
0.8gLactose
0.2gVitamin-mineral mix
Instructions
Combine all ingredients.
Each kitten should be fed around 18ml of formula per 100g of bodyweight to start with. If they are not gaining weight, then this should be increased slowly.
Once the formula has been made up, it can be kept at room temperature for an hour, or in the fridge for up to 24 hours. It must be thrown away after this, as bacteria love to grow in milk or milk replacers, and kittens can quickly become sick from drinking contaminated milk. Remember to warm it before feeding.
