Fleas are annoying. When my cats got them bad or was weeks of cleaning all the “soft fabricy things”, vacuuming, and flea baths.
Now is down to just a dose of advantage flea medicine on the back of her neck once a month (and still washing a lot, but she’s much better now)
I can only recommend advantage for the flea medicine in the back of neck. We tried a cheaper off brand and she was like…got very sick. Vet said it can happen, so I went back to the only one that she tolerates well.
