Why don't cats like onions? - in detail
Cats are known for their finicky eating habits and strong sense of smell, which play a significant role in their dislike for onions. Onions contain various compounds that can be harmful to felines, including thiosulfates and N-propyl disulfide. These substances can damage red blood cells in cats, leading to anemia. Moreover, the strong odor of onions is unpleasant to cats, who have a highly developed sense of smell. The pungent aroma can overwhelm their sensitive noses, making the experience unappealing. Additionally, onions are difficult for cats to digest due to their high fiber content and complex carbohydrates, which can cause gastrointestinal upset. In summary, the harmful compounds, strong odor, and difficulty in digestion contribute to a cat's dislike for onions.
