Tortilla chips are a snack food that is made from corn tortillas which are cut into wedges and then fried or baked.
They are made from corn , vegetable oil, salt and water.
Though usually made of yellow corn, they can also be made of white, blue, or red corn.
Some manufacturers include many other ingredients including wheat, sugar, and monosodium glutamate (source)
So can rabbits eat tortilla chips at all?
Unfortunately they cant eat them at all.
They are just too bad for them to eat and will harm them if they have too much of them.
They are fine for them to nibble on but nothing more than that.
