The problem with not knowing

It's that time of the year again, and I am wanting to have a pet at home. It would be great to have a cat or a dog to wake up to and play with. However, one of my ultimate fear about having a pet at home is fleas! My family had a pet cat one time that had a lot of medical issues including flea problem. Although, they managed to remove all the fleas using cat flea treatment. Maybe my issue about pets is ignorance. I should probably do my own research on the website I found, and I might change my mind about keeping a pet at home.
