How the calculator works
Newborn puppies and kittens are fed by body weight. Puppies need about 13 ml of made-up formula per 100 g of body weight per day in week 1, rising to about 22 ml by week 4; kittens need about 18 ml per 100 g per day. Lact-O-Cent is mixed at 1 g of powder to 3 ml of lukewarm water. Weigh daily at the same time and adjust as your baby grows.
For the full method, read our puppy milk replacer feeding guide and kitten milk replacer guide.
