I think I will check with our vet (when I actually get around to thinking about it during the day!) because I've been wondering about the whole cat shampoo issue myself.
I have 4 cats and as much as we all LOVE kitty bathing :wink: my one pound rat NEEDS a bath soon. He gets all greasy and stuff, I don't know how. Anyway, my other kitty (she's 17.5 yrs. old and as scrawny as they come) can not even wear a flea collar because the chemicals in them make her literally sick. I'm afraid if I'd ever put one of those back on her now it would kill her for sure. So we have made a collar for her....just a strip of material sewn up with lavender buds in it and tied around her neck. Seems to work, though she doesn't really go outside that much, but it doesn't make her sick. So I'm wondering......maybe a little lavender EO would be ok to add to a cat soap. Like I said, though, I'll be asking the vet before trying it.
