No, cats should not eat Alfredo, as the ingredients may be toxic or cause indigestion.
Alfredo sauce typically contains ingredients such as garlic, onions, dairy products (such as cream and cheese), and spices that are not suitable for feline consumption. Garlic and onions are toxic to cats and can cause digestive upset and red blood cell damage. Dairy products can also be harmful to felines, as many are lactose intolerant. You should avoid feeding cats Alfredo sauce or other human foods, and stick to a balanced cat food recommended by your vet.
