Published Categorized as About Fleas

There is no question that most people love onions, and there are plenty of different dishes that offer this tasty garnish. However, you must keep in mind, that just because you love the way an onion tastes, it can be extremely dangerous to your cat.

Onions contain thiosulphate, which is an ingredient that is toxic to cats when consumed. When onion is ingested by a cat it will cause a medical condition that is known as hemolytic anemia. This is characterized by an extensive amount of damage to the cat’s red blood cells. The toxicity in onions may cause the red blood cells that are circulating in your cat’s body to actually burst.
