PupCups are similar to Jell-O cups, but filled with water. It's for those times when your chihuahua needs a drink right now, and absolutely won't stop yapping 'til it gets a swig.

Out of Home Pet Products, the maker of PupCups, says their product is "Veterinarian Approved". But then again, what veterinarian would not approve water?

Obviously, the advantage to PupCups is that each container is small enough you can store it inside a purse, or coat pocket, and take it with you. It would work great for those people who don't like sharing their water bottle with Buddy. Moreover, it's not just plain old water, it's purified, with reverse-osmosis, and all that carbon-filtered technology stuff.

No word yet on how much each cup costs. They're available in select locations.
