102 DISEASES OF CATS 



In severe cases, in which the pharyngeal 

 lesions are accentuated, the infection extends 

 up the eustachian tubes, producing purulent 

 otitis, and is usually fatal. Depression is well 

 marked, anorexia complete, but thirst is exces-

In the absence of . gastro-intestinal compli-

 may give way to fetid diarrhea if the lower ali- , 

 mentary tract is involved, 



- In contra-distinction to the distemper of the' 

 dog, extension of infection to the bronchi and 

 lungs is comparatively rare, but if such hap- 

 pens the symptoms of bronchitis and pneumo- 

 nia either separately or associated, as the case 

 may be, make their appearance. The temper-

 auscultation and percussion. Unlike the bron- 

 cho-pneumonia of the dog, which is the typical

 pnevunonia of the cat is usually atypical; that 

 is to say, it may appear in the croupous form,
