Canned tuna, especially albacore, can contain high levels of mercury. Mercury is a neurotoxin that can accumulate in a cat’s body over time, leading to severe health problems. Smaller fish are safer.

- Potential Symptoms: Mercury poisoning in cats can manifest as neurological issues, including loss of coordination, tremors, and seizures.
- Type of Tuna: White tuna (albacore) generally has higher mercury levels than light tuna (skipjack).
- Moderation is Key: Even small amounts of tuna, when given frequently, can contribute to mercury buildup.
