Yes indeed.Please do not use the cheap stuff on ANY animal. More often than not it doesn't even work and then on top of that its so common to have health complications over it.
+1 To the above.Try a flea comb, with a container of warm soapy water at the ready to drown the fleas. Bathing in warm soapy water (using original formula Dawn) is also safe for small kittens and nursing mothers.
I was an LVT for 11 years and saw hundreds upon hundreds of animals have advantage applied with no reactions whatsoever so I would say this was an extremely rare case. Pyrethrums, however, can very commonly cause seizures and death in cats. This is the chemical used in many OTC advantage knock-offs and all other cheap flea treatments including collars. It is often marketed as "all natural" because it is actually a derivative of the chrysanthemum flower.Some cats are sensitive even to Advantage. A friend had a cat go into a seizure right after she put it on him. She had to give him a quick bath to get all trace of it off of him. With babies, I would go with a flea comb.
I forgot about capstar! Great suggestion. I do believe that it is used to quickly get the fleas that are present off and it is meant to be used in conjunction with a treatment program such as frontline or advantage.+1 To the above.
And you may even use Capstar on Mama kitty, babies have to wait a little longer before they can be dosed.
