Otto, Remy and Grisu were born in 2011 and died in 2013/2014. I had already posted on RatsLittlePaws.com an article about the three plus video (just uploaded again).
Kaya became with her almost 3 years, the oldest rat female that ever lived here (Remy had made it closer to the 3).
My first rat was called Sunny and if I remember correctly she turned 1 3/4 years old. At that time the subject of rats was totally new for me and compared to today I was a total layman.
