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 is generated by these two invariants together with the form "f" of degree 1 and order 4, the Hessian "H" of degree 2 and order 4, and a covariant "T" of degree 3 and order 6. They are related by a syzygy "jf"−"Hf""i"+4"H"+"T"=0 of degree 6 and order 12. The algebra of invariants of a quintic form was found by Sylvester and is generated by invariants of degree 4, 8, 12, 18. The generators of degrees 4, 8, 12 generate a polynomial ring, which contains the square of Hermite's skew invariant of degree 18. The invariants are rather complicated to
