Protein & energy bars — Food safety facts
Do not feed · Cats · full breakdown on the linked food page
Very often sweetened with xylitol or coated in chocolate. Treat every bar as toxic until you read the label.
Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.
Protein & energy bars should not be given to cats at all. Even a small amount can do harm, so there is no portion small enough to be safe.
Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.
Why these cautions matter
Even a gram or two of xylitol can trigger a sharp drop in a dog's blood sugar, and larger exposures go on to damage the liver.
Theobromine is the part that hurts. Pets clear it far more slowly than people do, so it builds up and reaches the heart and nervous system.
Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
