Cats that fetch are more common than you might think. New study finds 41% of felines retrieve

The next time you hear "go fetch" don't assume it's for a dog. 

Cats like to engage in the playful behavior more than people might think. A new study from researchers at the University of Purdue and the University of Pennsylvania found that 41% of cats fetch, compared with about 78% of dogs.

Mikel Delgado, a senior research scientist at Purdue who led the study, said prior to their research, it was well established that some cats play fetch. (Previous studies have documented fetching behavior among felines.) What stood out to Delgado was just how many cats retrieve.
