Give them a bath in the blue Dawn dish detergent. I'm pretty sure it kills fleas and is gentle enough to use on wildlife.
When I saw this question I immediately said, "Dawn. " I clicked the link to answer and see someone else has already answered the same. Dawn is what most people suggest and is safe to use on a young puppy.
When my girl was young I was advised that even the puppy flea shampoo wasn't safe because they are for older pups I think around age 10 weeks+. That's just my guesstimate. Like cobrien said it's safe enough to use on wildlife and it's what they use to clean all the oil spill covered birds.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
