Young/oldest rat

How old is the youngest and oldest rat you have right now? 

My youngest rat is from my last litter. Was born 2016.11.27. A soft little russian blue variegated dumbo. 

Oldest rat at my home right now. Is a very sweet old gentleman born 2014.04.30 Unfortunately, his back legs have started to give him some problems. He can still walk, climb around and do normal things. I do hope he will be with me some more time. But I'm prepared to help him cross over if it gets too tough to move or he seems to feel pain. 

#0: I think you may have missed a decade in the birth date of your youngest rat. :-)

#2 *Laughing* Just got the oldest rat in the world instead. Thank you for pointing that out. Shall change from 2006 to 2016 

My youngest is 2½ week and my oldest is actually Sankta Lucia - you know the female you help me get home from JDK -, 2 year and 2 month and a couple of days of age.

That is lovely, Here sister is also still in life, but don't live here. Sold here but got to use for one litter. 

She is a good rat, but not all of her offspring turned out well.
