Why Hard Boiled Eggs Over Raw Eggs?

You might wonder that an egg is just an egg, boiled or raw! What difference could it make?

The reason we humans won’t consider eating a raw egg is major because of its taste. But cats prey on nests for raw eggs! So what’s the actual deal?

The deal is that raw eggs are very fatal for cats as well as humans’ health. About 1 in every 20,000 eggs can contain salmonella or E. coli bacteria. This can upset a cat’s tiny stomach. Fever, diarrhea, vomiting, or cramps triggered symptoms.

Especially raw egg whites contain a protein called avidin, which prevents cats from absorbing necessary elements from eggs, so, eventually, it’s of no use for them. And you don’t want to feed a supplement which is only good at increasing unhealthy weight.

Whereas hard-boil (they’re cooked properly) eggs are very beneficial for a cat’s health, as they contain:

1. Animal proteinsGives the entirety of the fundamental amino acids which the cat’s body needs.

Fortunately, hard-boiled eggs are safe for cats. However, it does not imply that your cat can consume it daily, 1 egg a day for a 10 lb kitten is equivalent to 15 eggs a day for a 150 lb kitten. In layman’s language, if you feed your cat an egg, you should not give more than 1 in a day. The average grown-up cat should be eating only 400 calories a day.
