Short answer: Cats should not be treated to oatmeal cookies. A tiny crumb of plain cookie is unlikely to matter for most cats, but cookies are still a poor fit because they are usually sugary, buttery, and sometimes contain raisins, chocolate, or other ingredients cats should never eat.
Why oatmeal cookies are a bad cat snack
Even if oats themselves are not toxic, the finished cookie is a human dessert, not a cat food. The sugar and fat can upset the stomach, and add-ins are the bigger danger. Raisins, chocolate, and xylitol are all reasons to keep the cookie away from your cat.
If your cat stole one
If the cookie was plain and your cat only took a bite, monitor for drooling, vomiting, diarrhea, or unusual lethargy. If it contained raisins or chocolate, call your vet right away.

What to offer instead
Keep treats simple and meat-based. If you want to share something from your bowl, plain cooked oatmeal in a very small amount is safer than a cookie, but it should stay occasional. For the bigger picture, Cat Nutrition Basics is the better place to start.
