I'm sorry

it can be so hard trying to make the right decision for our babies. I have heard of more reactions with revolution than other anti flea products. A chemical the kills bugs isn't desirable to put on anything alive but having fleas isn't acceptable either. Everybody's body responds differently to different treatments- I feel blessed that Lilah doesn't have a bad reaction to flea medications and that my kids never had vaccine reactions, it is really scary when you are in the percentage of those that have a bad reaction. Right now we use advantage. There are several products like cedar neem oil blends that you can apply topically or apply preventatively if you don't have an existing flea problem, spray on fabric materials regularly, diatomaceous earth in the yard and broomed and vacuumed through the carpet but Those are all preventative- if you have an existing issue I personally advocate for removal through whatever means necessary and once the problem is solved then go back to holistic preventative measures. Good luck with your decision
