Best Flea Pills For Cats That Actually Work


Although cats, in general, are meticulous self-groomers they are defenseless in ridding themselves of fleas.  If your cat is not protected against fleas, they can cause severe problems.  The reason is that fleas feed off a cat’s blood so various diseases can spread through their blood system.  In addition, when cats groom themselves they could ingest the fleas and their waste and cause problems in their intestinal tract.  These are just two of the many reasons that you need to protect your cats from fleas using the best flea pills for cats.  Before you purchase oral flea medication for cats read the label because some will only kill adult fleas and others can kill the flea larvae.


How does it work?

Diseases cats can get if not protected from fleas

  • Flea allergy dermatitis—this is a common aliment and with each bite, it can cause minor skin irritation. The allergy can be caused by the saliva of the flea and can cause itchiness, aggravation, and irritation.
  • Tapeworms—this develop in the cat’s intestinal tract and can be caused by fleabites and ingesting fleas that are carrying the tapeworm larva when a cat grooms themselves.
  • Anemia—this occurs in flea infestations that are severe or in tiny kittens. As mentioned, fleas feed on blood and if many fleas are feeding significant blood loss can happen.
  • Hemobartonella—this is a blood parasite that attaches to the cat’s red blood cells and eventually destroys these cells that carry oxygen to the body.
