Why Raw Eggs Are Risky<\/h2>\n

1. Salmonella & E. coli<\/h3>\n

Raw eggs can carry harmful bacteria. While UK eggs with the Red Lion stamp<\/strong> have very low salmonella risk (hens are vaccinated), a small risk always remains. Cooking eliminates this risk entirely.<\/p>\n

2. Avidin & Biotin Deficiency<\/h3>\n

Raw egg whites<\/strong> contain a protein called avidin<\/strong> that binds to biotin (Vitamin B7)<\/strong> and prevents absorption. Over time, this can lead to:<\/p>\n

    \n
  • Dull, flaky coat<\/li>\n
  • Skin problems<\/li>\n
  • Lethargy<\/li>\n
  • Metabolic issues<\/li>\n<\/ul>\n

    Cooking denatures avidin<\/strong>, making biotin fully available. Egg yolks<\/strong> are actually rich in biotin<\/em> \u2014 another reason to cook the whole egg.<\/p>\n

    Nutritional Benefits<\/h2>\n
      \n
    • Complete protein<\/strong> \u2014 all essential amino acids for cats<\/li>\n
    • Taurine<\/strong> \u2014 crucial for heart and eye health (cats can’t produce enough)<\/li>\n
    • Vitamins A, B6, B12, D, E<\/strong> \u2014 immune support, bone health, energy<\/li>\n
    • Iron & selenium<\/strong> \u2014 supports immune system and thyroid<\/li>\n
    • Healthy fats<\/strong> \u2014 supports skin and coat condition<\/li>\n<\/ul>\n

      Not recommended.<\/strong> Salmonella risk and avidin (in raw whites) blocks biotin absorption. Always cook eggs thoroughly.<\/p>\n

      Are egg shells safe for cats?<\/h3>\n

      Yes<\/strong> \u2014 finely ground<\/strong> egg shells are a good calcium supplement. Bake shells at 180\u00b0C for 10 minutes, then grind to powder. Sprinkle a pinch on food.<\/p>\n

      Can kittens eat eggs?<\/h3>\n

      Yes<\/strong> \u2014 small amounts of cooked, mashed egg. Ensure eggs don’t replace their nutritionally complete kitten food.<\/p>\n
