Some flea medications can cause problems in cats. If the product you used is labeled for cats and is dosed appropriately Bella is unlikely to suffer any ill effects other than foaming at the mouth if the taste is unpleasant. If she begins acting strangely, vomiting or trembling I would recommend that you have her seen by your veterinarian. Most companies will list a customer service number on the package so you may contact the company with your concerns as well.
