The time to diagnose high blood pressure is before damage is done. Retinal hemorrhages and detachment can be avoided in a well-managed feline patient. I recommend that Doppler ultrasonic blood pressure measurements begin in all patients at an early age as part of their health care program.
Knowledge of breed predispositions and inherited disorders can direct your differential diagnoses and your diagnostic plan. For some of these diseases the genetic mutation has been identified and tests for the defect have been developed. For others, the phenotypical characteristics have been well-described but the genetic basis and mode of inheritance are unknown.
Cats with fevers (103? F-106? F) are a common occurrence in everyday practice. Most cases respond to antibiotic therapy or are self-limiting (abscesses, viral infections, post-surgical fevers). However, the most frustrating case is one in which a routine course of antibiotics does not improve the clinical condition of the cat, routine diagnostics do not identify the cause and the fever is ongoing.
