While you may feel like your pet is a part of the family, just remember that you cannot feed them as if they were, otherwise you could have a medical emergency on your hands. Here are several foods that either your dog or your cat should never eat so you can prevent this scenario from ever taking place.

Foods to Keep Your Cat Away From

1) Do not let your feline friend eat onions or garlic. According to a medical director at the Animal Poison Control Center at the ASPCA, cats are able to binge on caramelized onions, and the side effects of eating this forbidden food would mean that your cat's red blood cells are being depleted. This would cause anemia, which could exhibit itself in extreme fatigue and a lack of appetite.

2) Cats can get salmonella from raw eggs too. If your cat eats these, this could cause vomiting and diarrhea, as well as fatigue. In fact, your cat does not even have to eat the raw eggs to contract this; you could pass on salmonella to your cat unless you are careful to wash your hands whenever you handle raw eggs.

3) Alcohol is also a health hazard to your kitty. If this is mixed with milk or cream (like in a White Russian), your cat may be especially drawn to this. But alcohol is in some dough too. Whether you make it from scratch or buy it from the store, yeast dough can lead to a cat's stomach producing alcohol. In whatever form it comes, alcohol is toxic, potentially lethal for your cat. You want to be able to reach a vet before you start seeing serious symptoms such as seizures.

4) Raw fish, raw meat can lead to food poisoning, and even brain problems in your cat. This is because raw fish can deteriorate the B1 vitamin called thiamine, which your cat rather needs.

5) Tuna poses mercury problems for cats as well as for people. It can further keep your cat from being fully nourished. A couple bites of tuna every so often should not be injurious, but you definitely do not want this to be a regular part of your cat's food intake.

Dangerous Dog Food

1) You already knew that chocolate is toxic to dogs, and if you see your dog vomiting, with diarrhea, or even having seizures, then this could be a sign of chocolate poisoning. The darkness of the chocolate will determine how serious the poisoning is, as darker chocolate will mean a more serious case of poisoning.

2) Xylitol is also a danger to dogs. Yes, that is a real substance, and you can probably find it in your house if you have sugarless gum or candy, or baked goods that also use this artificial sweetener. If your dog ingests this, it could lead to lethal liver damage. It can only take 10 or 15 minutes after popping one piece of the sugarless gum for a dog to develop low blood sugar, and soon after to start vomiting and losing balance.

3) Kidney failure in dogs can be caused by grapes or raisins. If your dog is vomiting, urinating frequently, and extremely thirsty, your pet may have consumed this fruit.

4) Dogs and cats really do have things in common. Dogs cannot eat onions or garlic either. Just as with cats, a dog could develop anemia from eating this as these foods will destroy red blood cells. Again, a diminished appetite and extreme fatigue could point to this poisoning.

5) Alcohol is also a forbidden substance for dogs. Keep them away from alcoholic drinks of course, but also be aware that yeast dough (made at home or bought from a store) can lead to a dog's stomach creating the alcohol itself. This can be a lethal substance for dogs too.

Your job is a little trickier when it comes to dogs, as most of them are pretty open to trying anything that is potentially edible. You want to make sure that these dangerous foods cannot be reached by them, and that if you have children, that they are aware of what they cannot give to your pet. You may want to train your dog to drop things from its mouth at your command, so you can catch them before they eat something harmful.

You want to detect poisoning as soon as possible. If you have any suspicions that your pet ate something dangerous, do not wait to reach the ASPCA animal poison control center: 888-426-4435, or the Pet Poison Hotline: 855-213-6680. And if you want to create or change a diet for your pet, be sure to consult your veterinarian first.
