Dwarf rats are usually about 1/3 of an adult rat weight. They are cool little guys and great for people who want a pet rat but just do not have the space.
Dwarf rats can live just fine with normal sized rats. They all eat the same diets and require the same care.
A dwarf rats temperament will depend on the line, but most are exactly like their full sized counterparts.
The cool thing about dwarf rats is that they are much less prone to tumors due to their growth hormone being turned "off" They also smell less due to their small size.
