I've read all your posts about flea infestations. Thank goodness my babies do not have them but my daughter's Chester does. He has been given Advantage, Frontline & I think Revolution. They work for a while but then he's infested again. I told her to use DE but we need instructions on how to use it in the house. Chester is an indoor cat. My dght. has birds, we need to know what dangers to them. Also my dght. house is so cluttered I don't think she could get to all the carpeting. (Thank goodness she doesn't read this site, she would be mad at me.) I've told her she needs to get rid of the eggs. She takes him to the vet all the time for this medication but the vet is no help in advising how to remove the eggs. If someone could refer me to a good site it would be helpful. I've been online and know what the stuff is and where to buy it but not how to apply in a house and the dangers. Thanks
