Meerkat, named for its pop up like behavior, is a jQuery plugin created by Jarod Taylor. Meerkat, depending on the options you have set, will slide or fade in from the top or bottom of the browser window and remain in its fixed position while the rest of the page will scroll normally.

You have a choice of providing a close option which will simply close Meerkat until the page has been reloaded, or a dontShow option, which will close Meerkat until the browser session has ended, or for a set amount of days, depending on the options you have defined.

Whether it’s used as a simple promotional tool, a roost for advertisements, or even as an alternative to a splash or entry page; Meerkat is unobtrusive, cross-browser compatible, and degrades gracefully if Javascript has been disabled.
