If my cat has flea allergies, what products can I use, and would it mess with her advantage treatment? Or do I have to only use the advantage?

Advantage treatment is a good start. If your kitty has flea allergies it is necessary to keep fleas from biting her. So: Unfortunately fleas only hop on the body of your pet when they want to feed, then they hop off again and stay in your pet's environment. So you need to treat all pets in the household as well as the environment (which contains the fleas, their eggs and larvae). Flea treatment:  1) Get some flea medication such as a Flea spray or a spot on from a pet shop or your veterinarian (Advantage is fine) and apply monthly 2) get flea powder, put some in your vacuum cleaner bag and vacuum your house and furniture and also non-carpeted areas frequently to remove flea larvae and eggs which live off house dust. Dispose of the bag in the trash outside. Hot-wash all the pet's bedding, If you do this diligently for a few months you will get rid of the fleas.

    It's not recommended to combine a spot on treatment and a flea collar. You need to disinfect the environment, as that is where fleas live. They jump on the animal to feed, and then jump off. Wash Lincoln's bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Also make sure to flea treat your cats to prevent them from getting them. I hope this helps!
