My dogs lick the plastic on the shower curtain and, unfortunately, my legs when I get out of the shower. i have not been able to determine what they are missing in their diets that would cause them to do this. I think it is either something in the moisterizing soap or the water itself. The also try to lick the moisterizer off my legs, but I won't let them because it may make them sick and I don't want my legs to have "doggie breath". Also, I have had cats before and I believe they just sometimescrave attention. They do many things to get people's attention and perhaps that is what she is doing.
