No. Chocolate milk packages theobromine, lactose and sugar in one tempting drink.

Why it’s a problem

Chocolate milk carries a real theobromine dose from cocoa, though diluted compared to solid chocolate, and cats process theobromine very slowly. The milk base adds lactose most adult cats cannot digest, and the sugar makes it palatable enough that some cats drink more than a lick.

How to serve it safely

Keep chocolate milk and cocoa out of reach, and do not leave cereal bowls with chocolate milk residue unattended.

Warning signs to watch for

Vomiting, diarrhea, restlessness, rapid breathing, tremors and a racing heart, usually within hours.

When to call the vet

Contact a vet or pet poison hotline after any meaningful chocolate milk exposure — a small cat and a large lick change the math.

Common questions

Is a small lick dangerous?

A tiny lick of diluted cocoa milk is usually low risk, but call your vet with the amount for a proper assessment.
