hi tad,
there is not a mute option.
i'm sorry for your frustration. i can't imagine us ever answering "don't use the cattery" to a simple question of "is it possible to mute the food message?"
I can see us perhaps saying "that option is not available", or perhaps if it's frustrating to offer a solution of storing them in sl if the food reminder messages are causing you frustration.
feel free to IM me inworld if you wish to talk about this further.
thanks!
