ou may assume that fleas are harmless or that they only make your dog or cat itch a little. While this is true to a point, the first thing you should know is that fleas aren’t picky. They will feed on dogs, cats, reptiles, birds, and almost any other pet you may have.
The biggest danger of fleas is allergic reactions. When the flea sucks the blood out of you or your pet, you or your pet may suffer an allergic reaction to the flea’s saliva. The spot will also get itchy, and prolonged scratching can lead to infection.
Finally, if your pet is infected with fleas for a long time, they may suffer from anemia because of blood loss.
