Kitten Within the first 2 days after birth, kittens acquire passive immunity from their mother’s milk. Milk within the first few days of parturition is called colostrum, and contains high concentrations of immunoglobulins. These include immunoglobulin A and immunoglobulin G which cross the intestinal barrier of the neonate. The immunoglobulins and growth factors found in the colostrum begin to establish and strengthen the weak immune system of the offspring. Kittens are able to chew solid food around 5–6 weeks after birth, and it is recommended that 30% of their diet should consist of solid food at this time. The kitten remains
Conjunctive normal form formula_30 and formula_31 with a new variable, and repeating as often as necessary. To convert first-order logic to CNF: As an example, the formula saying ""Anyone who loves all animals, is in turn loved by someone"" is converted into CNF (and subsequently into clause form in the last line) as follows (highlighting replacement rule redices in formula_71): Informally, the skolem function formula_72 can be thought of as yielding the person by whom formula_60 is loved, while formula_74 yields the animal (if any) that formula_60 doesn't love. The 3rd last line from below then reads as ""formula_60 doesn't love the animal
