Theo was a black eyed white.
Theo came to me with his brother Luke having previously been a child's pets. The parents claimed the child had developed an allergy to them, but in my experience, children getting bored of pets is far more common than children spontaneously becoming allergic to them!
They were both around 10 weeks old when I picked them up, and neither had been handled much, though Theo was the more friendly of the two.
Theo, in contrast to his brother, was a simple rat to introduce, he kept himself to himself and never caused any bother. He was a gentle, well rounded rat and seemed well liked within the group.
Why Theo? My boyfriend Jon named him.
