Questioncan you keep two Russian box turtles in the same cage?
AnswerThere is no such thing as a Russian Box Turtle- do you mean a Russian Tortoise?
Russian Tortoises can get along fine as long as they have a large habitat, especially outside.
In general, tortoises don't like or want cagemates, so if they don't have enough room, they will often bully one another.
