Bovine Topologists

We are learning that some animals are much smarter than previously suspected.  For example, I read this week that experiments with pigeons showed they can effectively count objects and rank them by number of elements.  Before this research it was assumed that was a talent possessed only by primates.   So I am wondering:  Just how much do we know about the intelligence of other critters.  Could a raccoon understand algebra?  Maybe even calculus?   And cows are not considered the Einsteins of the animal kingdom, but how do we know they do not understand topology and just cannot let us know what they know.  After all, how much information can you convey when your only word is "Mooo"?  This photo is of a couple of cow pals who know what they see and are no doubt contemplating and discussing the four-dimensional reality of the 3D figure.  Hey!  It could happen.
