对猫狗有害的人类食物

A number of human foods are dangerous to pets. Many of these foods may seem tasty to our pets but can prove deadly if eaten. It can be very tempting to offer pets food from the table, but pets should not be given human food unless recommended by your veterinarian.

If you suspect your pet may have eaten a dangerous food, contact your veterinarian immediately. In many cases, early recognition and treatment are critical.

Chocolate, Coffee, and Caffeine

Chocolate contains theobromine, a chemical that is toxic to dogs in large enough quantities. Chocolate also contains caffeine, which is found in coffee, tea, and certain soft drinks. Different types of chocolate contain different amounts of theobromine and caffeine. For example, dark chocolate and baking chocolate contain more of these compounds than milk chocolate does, so a dog would need to eat more milk chocolate in order to become ill. However, even a few ounces of chocolate can be enough to cause illness in a small dog, so no amount or type of chocolate should be considered “safe” for a dog to eat. Chocolate toxicity can cause vomiting, diarrhea, rapid or irregular heart rate, restlessness, muscle tremors, and seizures. Death can occur within 24 hours of ingestion.

Grapes and Raisins

Grapes and raisins can cause acute (sudden) kidney failure in cats and dogs. It is unknown what the toxic agent is in these fruits. However, clinical signs can occur within 24 hours of eating and include vomiting, diarrhea, and lethargy (tiredness). Other signs of illness relate to the eventual shutdown of kidney functioning.

Garlic and Onions

Garlic and onions contain chemicals that damage red blood cells in cats and dogs. Affected red blood cells can rupture or lose their ability to carry oxygen effectively. Cooking these foods does not reduce their potential toxicity. Fresh, cooked, and/or powdered garlic and/or onions are commonly found in baby food, which is sometimes given to animals when they are sick, so be sure to read food labels carefully.

Many cases of human food toxicity in pets are accidental. A pet may find and chew on a package of gum or candy, or steal food from a countertop or table. The best way to prevent this is to keep all food items in closed cabinets or in areas that are inaccessible to pets. This may be particularly difficult during the holiday season, when more candy, chocolate, fruit baskets, and other food items are around. During these times, increased vigilance can help prevent pets from finding and eating dangerous foods.

Children should also be taught to never give candy, gum, or other human food items to pets.
