Can Cats Eat Goldfish: Everything You Need to Know

Goldfish are a popular type of pet that many people enjoy keeping in their homes. But, for cat owners, a common question that arises is whether or not their feline companions may eat the Goldfish. In this article, we’ll dive deep into the topic of whether or not cats can eat goldfish and provide you with all the information you need to know.


What motivates cats to hunt goldfish?

Cats are drawn to the fast movements and vibrant hues of goldfish. They are naturally curious and playful creatures, which sparks their fascination with the lively fish in the bowl or tank. Moreover, cats are natural hunters, and their instinct is to play with their prey rather than devouring it straight away. As anyone who has seen a cat toy with a mouse knows, cats enjoy watching their prey squirm and struggle to get away.

The Risks of Feeding Goldfish to Cats

While cats may be curious about goldfish, feeding them to your cat can pose serious health risks. Goldfish contain thiaminase, an enzyme that can break down thiamine, a vital B vitamin. Without enough thiamine, cats can suffer from neurological issues, including seizures, loss of appetite, and even death. Additionally, goldfish may contain harmful bacteria, parasites, or chemicals, which can also be dangerous for cats.

Are Goldfish Toxic to Cats?

Goldfish themselves are not toxic to cats, but they do contain bacteria that can be harmful.
