The reason why dogs and cats usually scratch themselves after getting flea bites is because of flea allergy. When the flea bites, it injects its saliva into the pet. This can cause allergenic reactions, which can last up to 2 weeks after the bite. The dog or cat will be scratching itself all the time and start losing hair in the infected area. If you look closer at the skin, you will find groups or clusters of small red dots. These are flea bites that can potentially cause flea allergy.
Cats are better than dogs at getting rid of the fleas. They simply catch and eat them. If they can’t get rid of the fleas by themselves, a safe way to help them is with a flea comb. Simply look through the fur for little black moving spots. Sometimes flea dirt will give them away. When the fleas lay eggs on your pet, they often fall off where your pet rests. Here, they continue evolving into larvae, pupae and lastly they turn into adult fleas. They mostly go through the pupal stage in 10 days, but sometimes it can last a whole year. If you search the area where the pet rests and the pet itself, you will find that only a small percentage of the flea infestation consists of adult fleas. Most of it is eggs, larvae and pupae. It might surprise you that the most common flea you will find on your cat and your dog is the cat flea.
Treating flea allergy
The best way to get rid of flea allergy is by getting rid of the fleas. In the worst cases, you will also have to supplement with different kinds of medication that stops the itching and treats the infected wounds. When the dog or cat itself is flea-free, you should continue to the area where it rests. Clean all blankets and vacuum daily to reduce the flea infestation to a minimum. To make sure the fleas don’t attack your pet again, you should apply flea drops (also called spot-on treatment) on the neck of the pet. Do this every four weeks during flea season for best results. Make sure you get the right product for your pet, as they differ depending on your dog or cats size. If you overdose, it can kill your pet. Be sure to read the instructions carefully. Most products kill and prevent both fleas and ticks at the same time, and the most popular ones are Advantage and Frontline.
There are many other ways to get rid of fleas, but the above has worked very well for me. You can also use flea collars, powder, pills, spray, shampoo and even flea bombs to get rid of fleas and treat flea allergy on your pets. Just remember to treat all your pets and do it on a regular basis. The best way to get rid of a flea infestation and flea allergy is to prevent it.
