Sundried raisins, not sulphured. Good to give?

[picopowerr]

So, I bought some raisins today.
They are sundried, no toxins or anything, nothing added except for a bit of olive oil.

Is it save to give this to my Caique?

He loves grapes but he is such a messy eater that the grapes are literally stuck on the wall, I have a dog and grapes are really toxic for them. My Caique eats the raisins with a lot less mess, so it's saver for my dog and my walls
