--When you are combing the fleas off - dipping them in the hot water is good but add a bit of DAWN dish soap to it and it really kills them instantly.
That's exactly what I did too! I love to see them little buggers fight for air. The fleas, I mean.

I bathe MooShoo and all my cats in Blue DAWN. It's the closest thing to their Ph.

The crew has stopped scratching, so that's a good sign. I never met a flea I didn't hate.
