My favourite one's were two boys called Morph (black and white) and Lennon (brown).
Morph was a bit dopey but he was so sweet, they used to run around my bedroom and climb up my clothes in the warbrobe and run up and down the clothes rail
Morph was a pig and I was always finding him in the bin looking for food scraps
At the same time as those two I had one called Zorba who was a girl, and she was so fast! Very clever and switched on. And a girl called Jasper who was a but vicious when I first got her but she chilled out in her old age and became very affectionate.
My first ever rat was called Jarvis and she was awesome, very loving. She had an accident in her wheel once and her tail got caught up and partially ripped off. I got her free though and she chewed her mangled tail off!! She lived a couple years after that though and coped fine with half a tail.
I also inherited my brothers boy rat, Beavis too cos he got bored of him.
He was lovely too, very like Morph.
I loved my Ratties, haven't got the patience for the cage cleaning these days though
