What type of food should be avoided for cats due to potential toxicity?

The appropriate food to avoid for cats due to potential toxicity is chocolate. Chocolate contains substances called theobromine and caffeine, which can be harmful to cats. While cats are less likely to consume chocolate compared to dogs, even a small amount can result in symptoms such as vomiting, diarrhea, increased heart rate, and, in severe cases, could lead to seizures or even death.

Onion, while also toxic to cats, can cause damage to red blood cells and should definitely be avoided. Chicken is generally safe and often recommended as a protein source for cats. Fish can also be a safe treat if given in moderation, although excessive consumption can lead to other health issues. Understanding the specific toxicities of different foods helps ensure the safety and well-being of feline companions.
