Unfortunately, complete flea control is not always possible for cats that live outdoors in warm and humid climates, where a new population of fleas can hatch out every 14-21 days. Some cats can be desensitized to the adverse effects of flea bites. This is an attempt to reprogram the cat s immune system so it no longer over-reacts to flea bites. If successful, itching no longer occurs or is less intense when the cat is bitten. This is often a necessary part of dealing with flea allergy.
Some cats respond best to long-acting injections and others to oral medication.
For this reason, the goal is to administer the smallest amount of steroid needed to keep the cat comfortable. Some cats develop a secondary bacterial infection in the skin. When this occurs, appropriate antibiotics must be used. An injection of steroids was given. Relief should be apparent within 12-24 hours.
