Some times you get an orphaned cat and you need to feed him, maybe you wonder where you'd get mother cat milk from, but guess what? you can make your own (substitute)!
12 oz. boiling water
1 envelope Knox unflavored gelatin
Dissolve the gelatin in the boiling water, and add:
1 12 oz. can evaporated canned milk
2 tablespoons mayonnaise
2 tablespoons plain yogurt
1 tablespoons light corn syrup
1 egg yolk
Mix well in mixer. Place in covered bowl and store in refrigerator. Warm a small amount for feedings. This will keep for about 7 days.
It adds between 15-20 grams on kittens a day.
