Our beloved pets, whether they have whiskers or tails, deserve the best care and attention. Part of this care involves ensuring that their diet is safe and healthy.

While it’s tempting to share our food with our furry friends, not all human foods are suitable for them. In fact, some can be harmful, even toxic. To keep your pets happy and healthy, we have you these 10 foods that are considered a big no-no for dogs and cats.

10 Foods That Are a Big No-No for Dogs and Cats

  1. Chocolate

Chocolate is perhaps the most well-known food that’s dangerous for pets. It contains theobromine and caffeine, both of which can be toxic to dogs and cats. Dark chocolate and cocoa powder have higher levels of these substances and should be avoided at all costs. Ingesting chocolate can lead to symptoms like vomiting, diarrhoea, seizures, and even death.

  1. Grapes and Raisins

Grapes and raisins may seem like healthy snacks for humans, but they can be deadly for dogs and cats. Even in small amounts, these fruits can cause kidney failure in pets. Symptoms include lethargy, vomiting, and a loss of appetite.

  1. Onions and Garlic

Onions and garlic, whether raw, cooked, or in powdered form, contain compounds called thiosulfate that can damage a pet’s red blood cells and lead to anaemia. Cats are particularly sensitive to these substances. Symptoms may not appear immediately but can include weakness, vomiting, and difficulty breathing.

  1. Xylitol

Xylitol is a sugar substitute often used in sugar-free gum, candy, and some peanut butter brands. It can lead to a rapid release of insulin in dogs, causing their blood sugar to drop to dangerous levels. This can result in seizures and even death.

  1. Avocado

Avocado contains a substance called persin, which is toxic to many animals, including dogs and cats. While the flesh itself is not as toxic as the pit and skin, it’s best to avoid feeding avocados to your pets altogether. Ingesting persin can cause stomach upset, breathing difficulties, and in severe cases, heart damage.
