Melaleuca/tea tree oil is highly toxic to cats and can cause severe neurologic depression.
Symptoms may appear within hours or may be delayed for days after exposure.
There is no universal safe dose. Risk depends on body weight, amount, product form, concentration, and the cat's health condition.

Melaleuca (Tea Tree) in fresh form still requires caution for cats.
Cooking does not automatically make melaleuca (tea tree) safe for cats.
Melaleuca (Tea Tree) powder is often more concentrated and easier to underestimate.
Melaleuca (Tea Tree) supplements and extracts may carry concentrated exposure risk.
Sauces, leftovers, seasonings, and processed foods may contain hidden melaleuca (tea tree) amounts.
There is no universal safe amount. Risk depends on your cat's size, the form of the product, and how much was eaten or licked. If the exposure was more than a tiny taste, or if drooling and weakness appears, contact a veterinarian.
Monitor for drooling and weakness, drooling, low appetite, behavior changes, or worsening skin irritation if the product was used topically. If symptoms are repeated, severe, or your pet seems weak, seek veterinary advice promptly.
Dilution can reduce risk, but it does not automatically make a product safe. Concentrated oils and extracts are more likely to irritate the skin, stomach, or airways, so exposure still deserves caution—especially in cats, small pets, and pets with underlying illness.
