My kitten brought a pleasant surprise of tape worms and fleas with her, when we brought her home. It took us a month before we figured either of these things out! We treated both the kitten and my older cat for tape worms, and fleas. We have also vacuumed EVERYTHING and washed all our clothing, and bed linens. We've checked both the cat and kitten for fleas since putting on the flea medicine and we cannot find any. However both the cat and the kitten are still itching! It has only been about 3 days since they've both had the flea medicine on, and we've been continuing to clean constantly since. Is there a chance that the cats are still fighting off the fleas? Or are we just being paranoid? If they can still be fighting of the fleas, is their anything we can do to kill all of the fleas? We weren't infested with fleas, we just wanted to be cautious so that we would not be in the future.
