Patent Claims:	1. A method to enhance the immune response of a feline to an antigen, the method comprising: administering to the feline in need thereof and to the mother of the feline while the feline is in utero, a pet food composition comprising: about 200 to about 1200 IU/kg vitamin E; about 50 to about 500 ppm vitamin C; about 0.1% to about 0.7% EPA; about 2400 ppm to about 7500 ppm choline; and about 0.1% to about 0.5% DHA, wherein the feline is a kitten born from a queen fed the composition prior to pregnancy and during the pregnancy; and wherein the kitten is also fed the composition prior to weaning and post weaning. 2. The method of claim 1, wherein the immune response is a humoral immune response. 3. The method of claim 1, wherein the immune response is an adaptive humoral immune response. 4. The method of claim 3, wherein the adaptive humoral immune response includes the production and release of antibodies against the antigen. 5. The method of claim 1, wherein the antigen is presented in a vaccine. 6. The method of claim 5, wherein the vaccine is feline panleukopenia, feline herpesvirus-1, feline calicivirus, feline leukemia virus, rabies, chlamydiosis, feline infectious peritonitis, Bordetella bronchiseptica infection, dermatophytosis, or giardiasis. 7. The method of claim 6, wherein the vaccine is rabies. 8. The method of claim 7, wherein an antibody titer in the kitten is increased as compared to kittens born to queens not administered the pet food composition. 9. The method of claim 1, wherein after weaning an antibody titer in the kitten sixteen weeks after vaccination is 50% to 150% higher as compared to kittens born to queens not administered the pet food composition. 10. The method of claim 9, wherein the vaccine is feline panleukopenia, feline herpesvirus-1, feline calicivirus, feline leukemia virus, rabies, chlamydiosis, feline infectious peritonitis, Bordetella bronchiseptica infection, dermatophytosis, or giardiasis. 11. The method of claim 10, wherein the vaccine is a rabies vaccine. 12. The method of claim 1, wherein the pet food composition further comprises an additional antioxidant. 13. The method of claim 12, wherein the additional antioxidant is one or more of beta-carotene, selenium, coenzyme Q10 (ubiquinone), lutein, tocotrienols, soy isoflavones, S-adenosylmethionine, glutathione, taurine, N-acetylcysteine, vitamin D, flavanoids, anthocyanindins, and/or lipoic acid. 14. The method of claim 1, wherein the composition further comprises about 2.5% to about 5.0% linoleic acid. 15. The method of claim 1, wherein the composition further comprises about 2.5 g/1000 kcal to about 7 g/1000 kcal lysine. 16. The method of claim 14, wherein the composition further comprises about 2.5 g/1000 kcal to about 7 g/1000 kcal lysine. 17. The method of claim 1, wherein the composition further comprises about 50 ppm to about 200 ppm manganese. 18. The method of claim 16, wherein the composition further comprises about 50 ppm to about 200 ppm manganese. 19. The method of claim 1, wherein the total amount of n-3 fatty acids in the composition is from about 1% to about 3%. 20. The method of claim 1, wherein the total amount of n-6 fatty acids in the composition is from about 3% to about 5%.
