Why can't cats have egg whites? - briefly
Cats should avoid raw egg whites because they contain avidin, a protein that can interfere with biotin absorption, potentially leading to nutritional deficiencies. Cooked egg whites are safer as heat deactivates avidin.
Why can't cats have egg whites? - in detail
Cats should not consume raw egg whites due to the presence of a protein called avidin, which can interfere with their health. Avidin binds to biotin, a vital B vitamin essential for maintaining healthy skin, coat, and metabolic functions in cats. When avidin binds to biotin, it prevents the cat’s body from absorbing this crucial nutrient, potentially leading to a biotin deficiency over time. Biotin deficiency can manifest in symptoms such as skin irritation, hair loss, and even more severe metabolic issues. While cooked egg whites neutralize avidin, making them safer for cats in moderation, raw egg whites pose a significant risk. Additionally, raw eggs carry the potential for bacterial contamination, such as Salmonella or E. coli, which can harm both cats and their owners. Therefore, it is advisable to avoid feeding cats raw egg whites and instead opt for cooked eggs if included in their diet, ensuring they are offered sparingly and as part of a balanced nutritional plan.
