Well, that's why I'm working on pulling up as many of the plants as I can right now. Maybe a bath for them once I get enough of it pulled up, otherwise they'd just go get more oil on them. BTW, cats hate baths...it's the equivalent of me trying to kill them, as far as how they react to it. But I'm definitely having a shower after every single one of my P.I.-pulling up efforts, even though I wear long gloves for this. Can't be too careful. And what I remove will go straight into the garbage bag! Geez...it's a good thing those kitties are so cute and lovable!
