Some  harmful foods to your pet includes:
  • Chocolates – especially dark chocolate – can cause hyperactivity, seizures, restlessness and vomiting about 2 to 4 hours after ingestion.


  • Caffeine – is also a stimulant (like chocolate) and can also cause hyperactivity, restlessness, seizures, vomiting and diarrhoea if consumed in excessive amounts.


  • Onions, garlic and chives – can cause gastrointestinal irritation, diarrhoea and red blood cell damage. Cats are especially sensitive.


  • Alcohol – can lead too much of the same symptoms as alcohol poisoning in humans, even if consumed in small quantities, because of the huge difference in the percentage water and increased metabolism in pets.


  • Avocados – contains a substance called Persin, that causes vomiting and diarrhoea. This substance is deadly to both rodents and birds.


  • Grapes and raisins – can cause kidney damage that can lead to kidney failure.


  • Macadamia Nuts – can cause weakness, tremors, vomiting and fevers within 12 hours of consumption.


  • Milk – can cause indigestion and diarrhoea


  • Raw potatoes – are considered poisonous to pets. 


  • Bones - will not only damage your pet's gums and chip it's teeth, but will probably also create an intestinal obstruction, or lead to constipation.
