Whether you are just going to get a cat or you are already a cat owner, you ought to be aware of the various kinds of human foods that are dangerous for felines. Yes, you got it right: some human foods can intoxicate your kitty or even kill it. You have to remember to avoid any of the products listed below because they can be hazardous to a cat's health.

List of foods which are dangerous for cats

A:
- Alcoholic beverages
- Apples and Apricots
(stems, seeds and leaves; see also: Fruit pits and seeds)
- Avocados. Seeds of this fruit can cause trouble with breathing, the chest, stomach (see also: Fruit pits and seeds).
B:
- Baby food containing onion (see also: Onion, Leek, Garlic)
- Baking Powder and Baking Soda
- Bones from fish, poultry or other meat. These products are hazardous because they can cause choking and internal organ damage: bones can easily splinter, cooked bones in particular. Choking signs are gasping, blue gums, face pawing, drooling, breathing difficulties, and loss of consciousness.
- Bread dough and Yeast dough. Dough continues to rise in the digestive system, which may cause pain or possibly rupture of the stomach or intestines. Moreover, alcohol, which is dangerous on its own, is also a byproduct of dough rising.
C:
- Cherries (see also: Fruit pits and seeds)
- Chocolate, Coffee, Tea and other caffeine can cause irregular heart beat, diarrhea, dieresis, lethargy, muscle tremors, and vomiting. There's also a risk of death. Anything with caffeine and/or Theobromine can affect the heart and the nervous systems.
- Citrus fruits and oil extracts
D:
- Dog food in large amounts can cause a metabolic imbalance because dogs do not require as much taurine as cats, and thus dog food does not contain taurine (and some other ingredients) in a sufficient amount.
- Dough (see also: Bread dough and Yeast dough)
E:
- Eggs. Potential risk of biotin depletion. Typical symptoms include hair loss, dermatitis, and retardation growth. Raw eggs may also contain salmonella.
- Eggplant (greens)
- Elderberry (see also: Fruit pits and seeds)
F:
- Fatty foods
- Fish, raw. Potential risk of thiamin deficiency. Typical symptoms include weight loss, weakness, uncoordinated rapport.
- Fruit pits and seeds can contain trace amounts of cyanide and are also a choking hazard.
G:
- Garlic (see also: Onion, Leek, Garlic)
- Grapes and raisins (see also: Fruit pits and seeds) can cause kidney damage; they are also a choking hazard.
L:
- Leek (see also: Onion, Leek, Garlic)
- Liver in large amounts. Liver contain a large amount of Vitamin A, which may result in Vitamin A toxicity. Typical symptoms include osteoporosis, deformed bones, bone growth/development issues.
M:
- Macadamia nuts (see also: Nuts)
- Milk and other dairy products. In theory, these can become a reason of diarrhea and loose bowels because many cats are lactose intolerant: adult cats do not have enough lactase enzyme to digest the milk sugar (while kittens do have the enzyme, and thus usual milk is okay for them). However, some adult cats can easily manage small amounts of milk without problem. If this is not your case, there are a special variety of milk (lactose-free) for cats and kittens. You can find this milk in most pet stores and shops.
- Mushrooms. Some kinds of mushrooms can affect multiple systems in your cat and result in a shock. It is safest to completely avoid giving mushrooms to your feline!
N:
- Nutmeg
- Nuts, especially Macadamia nuts and walnuts. They can affect the digestive and nervous systems of cats.

O:
- Onion, Leek, Garlic and containing them products including baby food. Cooked or not, onion (along with leek and garlic and other products of this type) can cause anemia by destruction of red blood cells. Even little amounts of onion are too toxic for a cat. Typical symptoms of onion / garlic intoxication include blood in urine, loss of appetite, lethargy, rapid heart beat, depression, and pale mucous membranes
P:
- Peaches and Plums (stems, seeds and leaves; see also: Fruit pits and seeds)
