There are two problems with giving your cat raw eggs. The first is the possibility of food poisoning from bacteria like Salmonella or E. coli. The second is that an enzyme in raw eggs, avidin, interferes with the absorption of the B vitamin biotin. This can cause skin problems as well as problems with your cat's coat.
Raw Meat and Fish
Raw meat and raw fish, like raw eggs, can contain bacteria that cause food poisoning. In addition, an enzyme in raw fish destroys thiamine, which is an essential B vitamin for your cat. A lack of thiamine can cause serious neurological problems and lead to convulsions and coma.
An occasional bite of dog food won't hurt your cat. But dog food is not a substitute for cat food. They do have many of the same ingredients. But cat food is specially formulated for a cat's needs, which include more protein as well as certain vitamins and fatty acids. A steady diet of dog food can cause your cat to be severely malnourished.
Liver can be healthy for a cat if the cat doesn't get too much. But eating too much liver can cause vitamin A toxicity. This is a serious condition that can affect your cat's bones. Symptoms include deformed bones, bone growths on the elbows and spine, and osteoporosis. Vitamin A toxicity can also cause death.
Sugary Foods and Drinks
Too much sugar can do the same thing to cats that it does to humans. It can lead to obesity, dental problems, and even diabetes.
Before it's baked, bread dough needs to rise. And, that's exactly what it would do in your cat's stomach if your cat ate it. As it swells inside, the dough can stretch the abdomen and cause severe pain. In addition, when the yeast ferments the dough to make it rise, it produces alcohol that can lead to alcohol poisoning.
Reacting to a drug commonly prescribed for humans is one of the most common causes of poisoning in cats. Just as you would do for your children, put all medicines where your cat can't get to them. And, never give your cat any over-the-counter medicine unless advised to do so by your vet. Ingredients such as acetaminophen or ibuprofen are common in pain relievers and cold medicine. And, they can be deadly for your cat.
