There has been some research and experiments that suggest the possibility that pets can be allergic to humans, but nothing conclusive. If there are cats or dogs with these allergies, they are extremely rare.
“Anything’s possible,” Deboer says. “But it seems clear that it is not very common, if it exists at all.”
