"I left him in a suspended animation kennel. Einstein never knew I was gone!"

A suspended animation kennel was a device invented by the early 21st century that allowed animals to go into suspended animation while their owners were away. When the animals woke up, it was like only a day had passed.


Dr. Emmett Brown placed Einstein in a suspended animation kennel in 2015 after finding out about Marty McFly's children, Marty Jr. and Marlene, and before he traveled back to 1985 in the DeLorean time machine to pick up Marty and Jennifer.

Doc retrieved his pet while Marty was running from Griff Tannen and his gang.

Behind the scenes[]

  • The plot point was added to explain why Doc left with Einstein in 1985 on his trip to the future, then came back without him on his return journey to collect Marty and Jennifer.


  • Suspended animation kennels have yet to be invented.
