Oatmeal is made of hulled oat grains – groats – that have either been ground, steel-cut, or rolled. Ground oats are also called “white oats”.
Steel-cut oats are known as “coarse oatmeal” or “Irish oatmeal” or “pinhead oats”.

As you can see, oatmeal contains a huge amount of phosphorus, acidic content, quite a bit of fat, and a hint of salt.
This means that they can eat a little dry oatmeal, but don’t feed them too much as it contains too much acidic content and phosphorus for them to handle.
Too much oatmeal may give them stomach problems.
