If you are tackling the job of mama for baby puppies or cats, don't let them aspirate (breath in) their milk, as it can cause respiratory problems and death. Feed only small amounts, and more often without allowing pup to overeat then vomit, and can inhale it into their lungs.
Don't use cow milk, but goat milk for babies is as good as the stuff from vet, easy to digest. Use l/2 goat milk (canned) for babies and 1/2 water. Remember to burp as with a baby on a bottle. Good growing.
