Yes, for some sense of thinking it is clear animals deliberate between options, which should be at least a necessary component of "reasoning". However, the big question in the linked article is whether this sort of thing is sufficient for the kind of abstract reasoning that humans regularly engage in. I would argue choosing between "run" or "fight" is different than choosing between "saving" and "spending". The latter requires an understanding of abstract principles and some mathematics, whereas the first decision can be based purely on weighing one's feelings.
