Can Cats Eat Ketchup?
Cats should not eat ketchup.Ketchup is mostly made up of processed carbohydrates and sugar, so it doesn’t provide the nutrients that cats need. Additionally, ketchup is very acidic, and can cause stomach problems and digestive issues in cats. Ketchup also contains a high level of sugar, which is bad for cats’ health.
