Aloha! You're speaking with Dr. Michael Salkin
I'm sorry that your question wasn't answered in a timely manner. It's unclear to me what you're asking. A three day old kitten won't eat solid food
but, instead, only milk and you should be offering a kitten milk replacer rather than cow's milk. These replacers can be found in pet/feed stores and the directions for their use are found on the label. If you don't have access to such a store, you can make up a replacer at home with the following recipe:
10 ounce can of goat's milk (lactose free if possible)
3 ounces of boiled water
1 cup of plain whole fat yogurt (live culture and lactose free if possible)
1/2 teaspoon white Karo syrup
1 large egg yolk (no white)
Feeding as much as the kitten will take from a small nursing bottle every 2-3 hours is necessary. Keeping the kitten in an 80F environment is necessary to avoid chilling.
Please respond with further questions or concerns if you wish.
