"It has long been known that rats engage in simple forms of play -- rough and tumble -- but we wanted to know if they could do more complex games, like hide and seek," neurobiologist Michael Brecht, an author of the study, published in the journal Science, told CNN.
Holed up in a laboratory with the rats and a selection of remotely controlled boxes, a team of scientists played a version of the childhood game with the rodents, teaching them how to hide from and find the researchers.
Over a period of a few weeks, they found that the rats quickly learned how to hide and seek -- and even started to develop tactics and strategies for the game.
...
But after being discovered, the rats would sometimes "re-hide," even if it meant a delay in receiving their reward -- proof, the scientists believe, that the rats were playing for the sake of it.
Although quiet when hiding, researchers said the the rats "squealed with joy" when they discovered the scientists -- something researchers think shows an understanding of the game's rules.
"They look like they're having fun, they come running," Brecht told CNN. "They're very vocal, they call all the time because they are thrilled about it. But then they hide, they are pretty silent," he said.

Articles like these are a good starting point when examining the ethics of killing animals
I'm honestly undecided on veganism or any stuff like that but it's readily apparent that any line drawn as to what animals are morally okay to test on and which aren't is entirely arbitrary. We can either test on any animals or none at all, really. Personally I lean towards the former.
She's been after the same rat for a few weeks, came home from the dog park and she cornered him in the bottom of my grill on the patio. I raised the lid and let it bang down, knocked the rat out of the bottom drain hole on the grill, stunned for about 2 seconds. Dog chose to bark rather than grab him, so he took off and made it to the fence
tl;dr: dog is loser, not ready for the revolution
