I don't think so... it seems to be really sensitive thought.
Once she felt in my mothers pool and she wouldn't stop scratching until I gave her a bath a couple of hours later. The next day she still scratched a little.
I should say that, even if she doesn't have any apparent skin problems (I've checked and it looks just fine and healthy) she scratches a lot sometimes.
Some time ago she had fleas so it was normal that she did so...
That's why I'm wondering about the baths frequency... does she scratch because I don't bathe her enough or because I do it too often?
