Kat, thanks for the hint about Foster & Smith -- they do indeed have what I need, for a lot less than I pay my vet for it. I have prescriptions from the vet, so I'll have to figure out the ordering procedure, but it looks like a good bet. I've bought flea stuff from them, but it never occurred to me to look there for much beyond that and dog beds and cat scratching pads.

Funny thing, though -- my first search term was "NACL," which the site responded to with "search term changed to 'nail'," and a selection of nail clippers...    Ah well, have to get our amusement where we can, I guess.

I think I've dealt with this enough for one night. Time to do something else.

Nancy
