Pocket Rats should not be confused with any other rodents 

 for they are unique in the possession of the following combina- 

 tion of characters; large mouse or small rat size; external, fur- 

 lined cheek-pouches; robust body; long, tufted tail; elongated 

 hind legs and weak forelegs; long silky pelage; and beautiful 

 color pattern. They are undoubtedly the handsomest of 

 North American rodents and are far removed from the mental 

 picture brought to the mind of the average person by the word 

 Rat. Irreproachable habits, gentle disposition and a cleanly 

 mode of life make fascinating pets of these dainty mammals. 



Pocket Rats are found in very much the same environment 

 as Pocket Mice, — prairies, arid plains, and deserts. The 

 greatest number of species and individuals is to be encountered
