Can guinea pigs eat oak?

Yes, they can eat it.

Just be aware that there is a risk of giving oak branches to them to chew on because of the potential of parasites on a branch like that so do be careful.

But I have given tree branches to my piggies without issue, but always make sure i check the branch carefully for any obvious dangers.
