HAAAAARRRRR, my post vanished in the depths of the internet!!!!!
OK, fleas: I have a product you can put in the neck of cats that kills the fleas and it works fine with my two cats.
It is absolutely normal that cats go underfoot! Sometimes it seems that it is normal for all pets, 'cause even my parrot rather walks than flies. One of my cats even throws herself into one's way to be carried into the house or to her bowl. She's soooooo lazy. And they always want to walk close to their people, so it can happen easily that they go underfoot.
JSmaz:Be prepared-none of our cats liked baths or being blow dried!
Jeni, none of my cats either! The problem was, that the humans had to be blow dried after the event.
