I brought Daisy home in November 2010. Daisy was a spaz when she was younger. Her nickname was 'Sheepie' because she was so fuzzy. She was hyper, she would hoard and hide all the treats or food she could find. She was 1st of my many rats to ever use a wheel. She loved running on that wheel. Daisy was the last of the pet rats I owned before my husband came to the USA in March 2011. (We are down to 3 boys and 6 girls). Daisy was also the last blue rat I've owned and the only Rex I've ever owned. She had Berkshire markings.
And here's a video of Daisy running on her wheel:
