2462. Preggar cat with poorer quality purring

A bright blue sky white cloud Sunday.  Pregger, an old cat with a few teeth left, was brought in  for anorexia 2 days. She was not drinking.

A very painful enlarged right submandibular lymph nodes and throat. Anorexia 2 days. Not drinking.  What is the cause? 

X rays show some opacity in the external ear canal near the right tympanic bulla. Is there a feline inflammatory polyp inside the external ear canal and the middle ear housed in the tympanic bulla? 

Anaesthesia showed no ulcers or decayed teeth but some tartar in the upper premolars. The cat was given antibiotics and for the last 5 days, no complaints so far.
