We already told you everything your cat can eat, and now it's time to go over what they can't.

There are some pretty unexpected items on the list, so even if you think you know which foods are toxic for your cat, it's probably best that you pay attention before you accidentally share the wrong snack with your feline friend.

It would be terrible if curiosity literally killed the cat.

Okay, so this one isn't so surprising, but it still has to be said that you shouldn't share your cocktail with your kitty. Even a few sips can cause things like vomiting, diarrhea, disorientation, and even death. So even if your cat seems interested in what you're drinking — it's best to just say no this time.

Caffeine

The last thing you want is a caffeinated cat running around your living room. But more than just making them super energized and restless, caffeine can also cause heart palpitations and muscle tremors. Keep that vanilla latte to yourself!

Eggs

While a few bites of your cheesy scrambled eggs are actually good for your cat since it will give them a nice extra dose of protein, raw egg is a big no-no. Letting your cat lick up those few drops of raw eggs you dripped on the floor while making breakfast can expose him to salmonella and other parasites that could lead to pancreatitis. That vet bill and your cat's health just isn't worth it.

Fish

Again, we're talking about the raw stuff here. It's easy to see how someone could think sharing sushi with a cat isn't a big deal. It is though. Besides giving your cat a serious tummy ache, raw fish can also break down an essential B vitamin in your cat called thiamine. This can result in neurological problems and lead to convulsions.

Grapes

Grapes and raisins are one of the most toxic foods for cats. Even a tiny amount can make your beloved feline critically ill. No one really knows why, but ingesting grapes can cause your cat to experience kidney failure. We don't have to tell you how serious that is, but it's not good.

If you think your cat may have snatched a couple of raisins or grapes off the counter, then watch for signs like vomiting (usually in the first 12 hours), lethargy, diarrhea, reduced appetite, abdominal pain, and decreased urination.

Milk

A kitten lapping at a bowl of milk is an iconic image that is often seen in movies and on tv. This explains why people are usually surprised to learn that giving your cat milk can actually make them very sick. This is due to the fact that as the cat reaches adulthood, it essentially becomes lactose-intolerance since it looses the ability to properly digest the milk.

Kittens younger than 4 weeks old that still need to be bottle fed should only be given special kitten formula from the pet store. *Never give cow's milk.

Onions

Cooked, powdered or raw — onions in any form are toxic for your cat. They're also bad for your dogs, but cats are twice as susceptible to the toxic allium components found in onions and chives. These components can damage red blood cells and lead to life-threatening anemia. Pass!

Raw Dough

Raw dough can release alcohol, which we already know isn't good for your kitty. The alcohol can then also cause your cat's stomach to expand.

If you think your cat was nibbling at your pizza dough that was rising on the counter, it's better to be safe than sorry. Get them to the vet ASAP.

Xylitol

Xyli-what? You may have never heard of it before, but xylitol is an artificial sweeter found in a ton of the snacks we eat. From gum to sugar-free candies and even toothpaste, it's everywhere and it doesn't take much to make your cat fatally ill. Xylitol causes insulin release in most animals, which leads to low blood sugar (aka hypoglycemia).

Early ingestions signs include vomiting, coordination problems, and lethargy. Within a few days, things can take a turn for the worst and your cat can end up dealing with liver failure and seizures.
