Scientists have found out which out of our feline or canine friends love us more.

As part of a new BBC2 documentary called "Cats v. Dogs", hosted by animal experts Chris Packham and Liz Bonnin, a neuroscientist has investigated which species prefers humans. We already knew that, like humans, dogs release the 'love hormone' oxytocin. This test has never before been done on cats.The neuroscientist checked the oxytocin levels in both cats and dogs after playing with their owners. He took saliva samples from 10 cats and 10 dogs on two occasions - 10 minutes before a playtime session with their owners and immediately after - and tested both samples for  oxytocin.
The results show the hormone increased by an average of 57.2 per cent in dogs but only by 12 per cent in cats. This means in theory, dogs love their humans more than cats do.
