There are many human foods that are toxic to a cat:
Chocolate - Can affect the heart and nervous system causing excitement / nervousness / trembling, vomiting / diarrhoea, seizures, muscle spasms, coma and death.
Caffeine - Can affect the heart and nervous system and causes the same or similar symptoms as chocolate.
Alcohol - Giving a cat alcohol repeatedly (or a lot of) will cause liver damage, breathing difficulties, coma and even death.
Garlic (any form) - Can damage red blood cells and lead to anemia.
Onion (any form) - Can damage red blood cells and lead to anemia. Onions are more toxic than garlic.
Tomatoes (all aspects of the fruit and plant) - Can cause the digestive, nervous, and urinary systems, but mostly causes severe digestive upset.
Potatoes (Raw and plant) - Can cause the digestive, nervous, and urinary systems, but mostly causes severe digestive upset.
Mushrooms - Some species of mushroom are highly dangerous as the can cause shock and even death.
Grapes and Raisins - It is unknown why these are toxic, but even a tiny amount can severely damage the kidneys.
Macadamia Nuts - Can cause gastrointestinal upsets, lethargy, vomiting and muscle tremors or stiffness.
Foods that are potentially harmful:
Liver (in large amounts) - A small bit of raw liver on occasion is very beneficial to a cat.
COOKED bones and fish bones (including raw and cooked) - Cooked bones are very hard and brittle and will splinter which can cause obstruction or laceration in the digestive system. Raw bones are much safer as they are soft and do not splinter.
Dog Food - Dog food is vastly different to cat food so doesn't have the added Vitamins and Fatty Acids cats need, such as Taurine.
Foods high in Salt and Sugar - Too much of both can harm your cat's health (sugar can cause obesity and Diabetes and salt will cause a chemical imbalance, as well as dehydration).
Milk - Cow's milk, despite popular belief, is not tolerated by many cats as many are lactose intolerant. An adult cat gets no nutrition from any sort of milk, but specially formulated cat or kitten milk can be used as an occasional treat.
Kittens and cats are strict carnivores. They get all their nutritional needs from meat. Kittens in particular, need a lot of Protein and Fat in order to grow and develop in a healthy manner. Kittens should be fed small meals at regular times, and should be allowed to eat as much as they wish. Young kittens should be fed four to six meals a day, while older kittens (around 6-9 months) will be able to eat larger portions three to four times a day. Don't be surprised if you are feeding your kitten much more than you would an adult cat, this is normal and growing kittens need all the nutrients they can get.
Due to the amount of food kittens can eat, it makes sense to feed a good quality cat food. The higher the meat content, the better. The best cat foods are the ones with a very high, named-meat content. They should be labelled by source, such as: Chicken, Turkey, Rabbit, Lamb, Tuna, etc., as the first, or first two ingredients. Generally speaking, kittens will become fuller much quicker on higher quality foods, and will eat less than if on lower quality foods.
It is advisable to stay away from brands that include Corn, Wheat, Cereals, Gluten and Soy in their foods - kittens and cats have difficulty in digesting these and can cause upset stomachs (diarrhea can quickly become fatal to kittens as they dehydrate easily), and do not provide any nutritional value to the kitten whatsoever. Wet food with these specifications are much easier to find than in dry food.
Moisture is very important to cats and kittens alike. While fresh water should always be available (cow's milk should never be given as this can often cause upset stomachs), the easiest way in getting water into kittens and cats is to provide wet food as the majority of their diet. Felines have evolved to get all their needed moisture from their prey (their ancestors were cats that lived in very dry and arid environments where water was hard to come by), so therefore have a low "thirst drive" and will not often seek out water on their own.
Canned or pouched food has anywhere between 60 to 80% water. Seeing as in the wild a cat's prey is around 65%-75% water, wet food provides a cat or kitten with more than enough water each day.
Definitely stay away from Fancy Feast and the like, as it's the cat equivalent of McDonald's, according to my vet.
The nice thing about cats is that they won't usually eat things that are bad for them. Dogs are much more prone to accidentally kill themselves with food. Cats can be fed some things that dogs shouldn't be fed such as chicken with bones and fish with bones -- the dog will chew the bones and possibly choke or cause intestinal damage, whereas the cat will eat around the bones.
Unfortunately, this makes it a possible problem to find a dry food the cat WILL eat.
There are lots of things cats can't (or at least shouldn't) eat, including onions, grapes, and chocolate. A cat's liver is much less effective than a human's at metabolizing certain compounds, so these foods, which are harmless to humans, are toxic to cats. Also, chemicals and pollution can make them very sick (many chemicals can even kill them).
They are carnivores, so they really should not be eating much, if any, plant based foods. They shouldn't eat milk or sugars (cats are actually lactose intolerant, and milk causes diarrhea).
Obviously, plastics, paper, or any other non-organic (not from living things) materials are not good (possibly even fatal), for cats.
There are lots of thing a cat should not eat.
-Garlic
-Grapes
-Raisins
-Tomatoes
-Chocolate
-Alcohol
And many other things. If you have a cat you have to stay away from the human food. Tuna may be an exception. If you don't give your cat these foods I'm sure it will live a happy life!
Theobromine in chocolate can cause theobrimine poisoning, although few cats will eat chocolate anyway. Large amounts of onion or garlic are also poisonous to cats.
Chocolate and Candy.

Cats should not eat tissues.
If you are in the woods with no food or nothing you should eat a cat. What ever moves its edible to eat like Deer's, Cats, Wolfs, Dogs, and rabbit's.

You should do proper cabling and protect your cables to prevent the cats from eating your wires.
No. Go eat cats. *EDIT - The question is not clear.
No because corn is human food and cats should eat food that is made for them only.
