1. Why Are Onions Toxic to Cats?
Onions are toxic to cats due to a compound called N-propyl disulfide. This substance damages red blood cells, leading to anemia.
The N-propyl disulfide found in onions causes a breakdown of red blood cells in cats, leading to a condition known as hemolytic anemia. According to the ASPCA, plants in the Allium family, including onions, garlic, leeks, and chives, contain organosulfides, which are toxic to both dogs and cats, with cats being particularly sensitive. This damage reduces the ability of red blood cells to carry oxygen throughout the body, which can cause severe health issues. It’s not just raw onions that are harmful; cooked, powdered, or dehydrated forms are equally dangerous. To ensure your cat’s safety, it’s crucial to avoid feeding them any foods containing onions. Remember, at solcat.net, you can find more detailed guides on maintaining a balanced and safe diet for your feline companion.
2. How Much Onion Is Too Much for a Cat?
Even a small amount of onion can be toxic to cats. The severity depends on the amount consumed and the cat’s size.
While the toxic dose is generally considered to be around 5 grams of onions per kilogram of body weight, even smaller amounts can cause significant issues, especially with concentrated forms like onion powder. According to a study published in the Journal of the American Veterinary Medical Association, onion toxicity has been reported in cats after ingesting as little as a teaspoon of cooked onions. The danger lies in the cumulative effect; even small, repeated exposures can lead to anemia over time. For example, if your cat weighs 4 kilograms (about 8.8 pounds), as little as 20 grams of onion could be harmful. It is vital to be vigilant about what your cat ingests. At solcat.net, you’ll find resources that help you calculate safe food quantities for your pet, ensuring they remain healthy and free from toxic substances.
