Hi there!
Our team double checked our alert system, and everything seems to be working normally and alerts are being sent out as they should be to users.
With that being said, Food and Milk warnings for the Cattery are only given as an Instant Message In-World. This means that you might not see them if your messages have been capped within SL. If you have the SL option to forward Instant Messages to your email enabled, the you could receive them there as well.
There is also a setting in the online Cattery that allows you to set a custom number of bowls left for when the Cattery will start alerting you. This means that you can set the cattery to start alerting you when your supply is starting to get low so you have a bit of extra warning and time to refill your stock before they are out. (instead of being notified when there is only 1 bowl left or when there is none left.) This also gives users a bit of extra chance to get the alerts if their SL messages often get capped.
We have a great manual page that goes over many of the cattery settings, including setting up the alert with a custom number of bowls left. You can check it out here:

I hope this information helps, if you still have any questions, please feel free to file a support ticket and our team will be more than happy to go into further details about your case and assist you further.
Thanks,
