Toxic — call your vet now

Why: Chocolate milk combines two problems: the chocolate (theobromine and caffeine, toxic to cats) and the milk (most adult cats are lactose-intolerant). Even a small amount should be treated seriously.

If your cat ate chocolate milk: Call your veterinarian or ASPCA Animal Poison Control at (888) 426-4435 immediately. Note how much was drunk. Vomiting, restlessness, a racing heart or tremors need emergency care.
