Among the many fish options available, mackerel often catches the attention of cat owners due to its rich flavor and nutritional benefits. But can cats eat mackerel safely?

Mackerel can be a nutritious treat for cats when served in moderation. Its nutrient-rich profile offers several health benefits that support your feline’s overall well-being.
