Loving pet owners everywhere tend to be overcome with compassion at the sight of their pets begging them for food as they sit and enjoy dinner or some other meal.

Since we love our pets, it can be overwhelmingly tempting to give in and feed them some scraps from the table. However, this could be a serious mistake. Just because a certain kind of food is good for humans does not mean that it is also god for cats or dogs.

Indeed, some of our favorite foods can turn out to be downright poisonous to our pets.

Here are a few common foods that we advise you to never feed them.

1. Macadamia Nuts


The next time your dog is begging for a bite of a cookie, be extremely careful about what you decide to share. Macadamia nuts are poisonous to dogs. They can cause vomiting, tumors and lethargy in your dog, and while they are not as poisonous as some other foods, veterinary care will still be required if your pooch should happen to eat any of them.

2. Bread Dough


If you bake some bread, it might be okay to feed it to your cat or dog after it has been baked. You should never feed raw bread dough to cats or dogs under any circumstances, though.

The yeast in the bread dough can have a similar effect upon a pet as alcohol poisoning might upon a human, since the yeast will expand in your pet’s stomach and produce alcohol. This can lead to everything from disorientation and bloating to tremors, vomiting, hypotension, hypothermia and even respiratory failure.

3. Avocados


Avocados can be great if smeared on some toast or enjoyed as part of a salad. They’re not for your pets, though.

Specifically, the avocado bark contains a chemical called persin, which can produce vomiting and diarrhea in dogs. Avocados are even more toxic to birds. Birds who eat them can end up having difficulty breathing and congestion around their hearts.

4. Cherries, Peaches and Apples


These fruits are all delicious. However, their pits or seeds contain trace amounts of cyanide. While the doses found in them are not high enough to be toxic to humans, the story is quite different for pets.

5. Coffee or Energy Drinks


Coffee or energy drinks can provide a great pick-me-up when we’re feeling sluggish or weak. They do not have the same effect on your pets.

In fact, the effects on cats and dogs of caffeine can be much more dire — including, but not limited to, such things as excessive urination or thirst, diarrhea, vomiting, a highly elevated heart rate, seizures, shaking and even death.
