Arinella's Bitsocker, called Socker (meaning "Sugar") was a silver fawn male that was born on the 23rd of July 2001. Socker turned aggressive so I had to put him to sleep.
Socker's father was Aristoteles Iso, and his mother was a beige female from another rat breeder. So every time you mate a truly good rat (which Iso certainly was) to any rat that is not closely related to him, or bred for temper for years and years you take a big chance and might just as well get some biters.
