It is recommended that dogs and cats not be bathed for at least 2 hours following application of the spot-on, however, if you want to play it safe, I recommend keeping the animal dry wherever possible for the first 2-3 days following the application of any spot-on, just to be sure. The article below (studied and sent in for publication by the Revolution manufacturer) only bathed cats 24+ hours after the spot-on was applied, so I can not say for certain whether Revolution flea control will remain effective in this species if you wet it less than a day after Revolution application. If you want to play it safe, leave cats and dogs unwetted for at least 24 hours (or, better yet, 2-3 days) after application of the Revolution for pets product (but don't panic if your pet gets wet a little sooner - Pfizer has done the tests and the product will most likely be water-fast should your pet sneak off for a quick dip in the pool a bit sooner than you expected).
