Are you slowly poisoning your animals?

There are, as you may know, foods that are harmful to animals.
Have you ,unknowingly been poisoning your loved one with deadly treats? read on, and discover what is what.

Toxic Foods for Cats
There are various foods that are toxic to cats. Unfortunately, there are many we are not often aware of that are just as dangerous. Below is a list of common foods that are harmful to cats.

Onions, Garlic, & Related Root Vegetables:
Onions contain a substance (N-propyl disulphide) which destroys red blood cells in the cat, causing a form of anemia called Heinz body anemia. Garlic contains a similar substance in a lesser amount.
Tomatoes and raw green Potatoes: These foods are members of the Solanaceae family of plants, which includes the Deadly Nightshade, and contain a bitter, poisonous alkaloid called Glycoalkaloid Solanine, which can cause violent lower gastrointestinal symptoms.
Chocolate/Caffeine: Caffeine and other stimulants, including theobromine (found in chocolate), can poison cats. Do not feed your cat these "people foods" or leave them out where the cat could reach them. It is wise to just feed cats a commercially prepared cat food and never feed them foods meant for humans, especially "sweets."
Grapes and Raisins: Recently discovered to be harmful to dogs, it is also believed that these fruits may also affect cats adversely.
Milk: Milk is not toxic, but because many cats are lactose-intolerant, which means that the lactose in milk and milk products produces stomach upset, cramps, and gassiness. If your cat loves milk, and begs for it, a small amount of cream may be okay, two or three times a week. (The more fat in the milk, the less lactose it has.)
Bones: from fish, poultry, or other meat sources: These bones can cause obstruction or laceration of the digestive system.
Dog Food: repeated feedings may result in malnutrition and diseases affecting the heart.
Mushrooms: Mushrooms can contain toxins, which may affect multiple systems in the body. these can cause shock, and even death. This is for unpicked mushrooms found in forests, not the button mushroom variety, but I wouldnt test this theory, just in case the normal supermarket bought ones are just as deadly...
Raw Eggs: Raw eggs contain an enzyme called avidin, which decreases the absorption of biotin (a B vitamin). This can lead to skin and coat problems. Raw eggs may also contain Salmonella., which is deadly to humans, resulting in severe food poisoning.
Raw Fish: Eating raw fish can result in a thiamine (a B vitamin) deficiency leading to loss of appetite, seizures, and in severe cases, death. More common if raw fish is fed regularly. So NO SUSHI!

Toxic Foods for Dogs
As we know, Chocolate contains theobromine, a compound that is a cardiac stimulant and a diuretic.
Signs of overdose can be delayed for a few hours.
Symptoms include Staggering, labored breathing, vomiting, diarrhea, abdominal pain, tremors, fever, heart rate increase, arrhythmia, seizures, coma, death.
Cocoa powder and cooking chocolate: are the most toxic forms as they contain 10 times more theobromine than milk chocolate. A 10KG dog can be seriously affected if it eats a quarter of a 250g (about 60g) packet of cocoa powder or half of a 250g (125g)block of cooking chocolate.
Semi-sweet chocolate and dark chocolate: are the next most dangerous forms, with milk chocolate being the least dangerous. A dog needs to eat more than a 250g block of milk chocolate to be affected. Obviously, the smaller the dog, the less it needs to eat.
Onions, garlic and root vegetables: Onions and garlic contain the toxic ingredient thiosulphate.
Pets affected by onion toxicity will develop haemolytic anaemia, where the pet’s red blood cells burst while circulating in its body.
Symptoms include Hemolytic Anemia, labored breathing, liver damage, vomiting, diarrhea, discolored urine.
While garlic also contains the toxic ingredient thiosulphate, it seems that garlic is less toxic and large amounts would need to be eaten to cause illness.
Mushrooms: Mostly for Amanita varieties: If in doubt, if it has a white ring just below the hood, is brightly coloured, slimy, spotted or smells suspicious, its poisonous.
Symptoms include Abdominal pain, drooling, liver damage, kidney damage, vomiting diarrhea, convulsions, coma and eventual death.
Grapes and raisins: Like for cats but this is dependant on the amount ingested. Toxic from 256g (9 ounces) to 908g (2 pounds). Symptoms incluse, vomiting, diarrhea, abdominal pain and lethargy.
Nuts:Macadamia nuts are another concern, along with most other kinds of nuts. Their high phosphorus content is said to possibly lead to bladder stones. Dogs develop a tremor of the skeletal muscles, and weakness or paralysis of the hindquarters. Affected dogs are often unable to rise and are distressed, usually panting. Some affected dogs have swollen limbs and show pain when the limbs are manipulated.
Bones from fish, poultry, or other meat sources:Can cause obstruction or laceration of the digestive system.
Cat Food: Cat food is generally too high in protein and fats.
Fat Trimmings: Can cause pancreatitis.
Milk and other dairy products: Some adult dogs and cats do not have sufficient amounts of the enzyme lactase, which breaks down the lactose in milk. This can result in diarrhea. Lactose-free milk products are available for pets.
Raw Eggs:Contain an enzyme called avidin, which decreases the absorption of biotin. This can lead to skin and hair coat problems. Raw eggs may also contain Salmonella.
Raw Fish: Can result in a thiamine deficiency leading to loss of appetite, seizures, and in severe cases, death. More common if raw fish is fed regularly.

For both and other animals
alcohol: Any type of alcohol can be poisonous to your pet and aside from intoxication, can cause a coma or even death.
Apple seeds: Contain cyanogenic glycosides, resulting in cyanide poisoning.
Apricot pips:
can cause obstruction of the digestive tract.
Avocadoes: The toxic ingredient in Avos is Persin. most accounts of posoning have been in livestock which have eaten all parts of the avo, and in large amounts. The toxin may be confined to the leaves, bark, skin and seed, but the flesh is thought to be toxic to birds.
Cherry pips
Peach pips: can cause respiratory difficulties such as breathing, couging and sneezing.
Hops: May cause panting, elevated temperature, increased heart rate, seizures and possibly death.
Rhubarb leaves
Sugar: Can lead to obesity, dental problems, and possibly diabetes mellitus.
Salt: In large quantities can cause electrolyte imbalances.
Tea: Can have varied effects in pets, as each type of tea has a different amount of caffeine.

  1. Yay, thanks for spreading the word. It really irks me when people try and make out dogs (and cats) to be anything other than carnivores. Even this one dog-whisperer whose dog skills I otherwise respect encourages people to feed their dogs the same feed you eat. Presumably this would include onions. Good thing onions need a sizeable dose to do harm (as I understand it).

  2. Well, in Italy they do feed their animals exactly what human eat, so I suppose there are a few loopholes, the main thing is to make sure its not harmful. Take my dog for example, because he is still a pup, he enjoys everthing from oranges to socks and cushion stuffing...
