No support here, and there's a good reason why (at least I think it's good!).
This game is largely centered around keeping users involved and active on the site. Some things are necessary to receive alerts of course, like Rmail, subsc[injection]ription notifications, and auction notifications. Those are all things that require more immediate action; they are activities that are performed on a daily basis and/or involve competition with other players.
If we keep adding alerts for everything, pretty soon the site isn't gonna be much fun, everything will just end up being "oh, alert, time to do XYZ, blah..."
It takes 10 days in dying status before a pet hits the grave. That means that if your pen runs out of food and your pets are at 70 hunger, you have approximately 17 days before those pets go into the grave. There is no reason that we can't take a quick trip to our profiles and check the status of a pet's hunger once every week or two, and check the food pen to see if it is indeed still stocked.
Making an alert to let you know the pen is out of food just seems to take something away from the game; this is about interaction with virtual pets, after all. =)
