Paws in the Park

Okay I have a silly question about that event. Well, two questions. First, can anyone tell me when that event is? I can't seem to locate the post on that and I couldn't find it in the events. And my other question is that, I know this is generally an event for dogs, but I know you can get in free with a bag of food. Does that also include cat food? The only reason I ask is because Mom has an unopen bag of my food from before I had to switch to urinary food, so she would be happy to donate that. It is Natural Choice Indoor Adult, nothing crappy, I just can't eat it anymore! So let me know!
