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
Invariant of a binary form invariant polynomials on "V". Invariants of a binary form of degree "n" correspond to taking "V" to be the ("n" + 1)-dimensional irreducible representation, and covariants correspond to taking "V" to be the sum of the irreducible representations of dimensions 2 and "n" + 1. The invariants of a binary form form a graded algebra, and proved that this algebra is finitely generated if the base field is the complex numbers. Forms of degrees 2, 3, 4, 5, 6, 7, 8, 9, 10 are sometimes called quadrics, cubic, quartics, quintics, sextics, septics or septimics, octics or octavics, nonics, and decics
