My cat has gotten fleas somehow, even though she never goes outside. I vacuumed the whole place, sprayed flea killer on everything, and gave her a flea bath. She handled the bath much better than I thought she would. She howled a little at first, and squirmed a bit, but she eventually relaxed a little and let me finish. I'm sure it is not the last I will see of the Fleas, but at least the problem is lessened.
