Anchovy — Food safety facts
Feed with care · Cats · full breakdown on the linked food page
Extremely salty, whether fresh or tinned. A tiny piece at most, and no oil-packed ones.
Short answer
Yes, Caesar dressing often contains anchovy paste. The main risk is the high salt content, which can cause vomiting, diarrhea, or excessive thirst in cats. Just a lick is unlikely to cause serious harm, but watch for those signs. If your cat seems unwell or drinks a lot more water than usual, contact your regular veterinarian.
