Flea treatments like Advantage II are generally well-tolerated by cats, but some may experience temporary lethargy or other mild reactions. If she's just a little bit sleepier than usual but eating and drinking normally, it could be a transient side effect. However, always trust your instincts as a pet owner—if you feel something isn’t right or if you notice additional symptoms such as vomiting or excessive drooling, it's best to have her checked by a professional.
If this is an emergency, please seek immediate veterinary care.
