Hedgehogs may look cute and illicit an "aaaaawwww" response , but they are a walking flea-bus !!
They inherit them from their mothers in the nest, but hedgehog fleas are very different to those found on dogs or cats. Hedgehog fleas only live on hedgehogs.
If one finds itself in the dense, warm coat of a dog or cat it immediately knows it's in the wrong place and drops off to wait for another hedgehog. The same goes for hedgehog fleas that get onto humans, they do not stay long before leaving to find a hedgehog to live on. Likewise they wont get into your carpet and furnishings either. (Well they might, but they're not dangerous to you or your cats)
HOWEVER !!! Never spray a hedgehog with flea spray. You'll end up with a dead hedgehog. If it's completely infested, the only safe product to use is a pyrethrum based powder.
Has she started making "noises" yet?

I'm not saying any more - just wait !!
Weird creatures hedgehogs !
