Do you know if the people knew it belonged to them? A lot of people will grab cats like that thinking they're strays.
I ended up setting off my corn allergy again. I thought I was well enough to go back to eating some corn, so I got my vegan ice cream which has dextrose in it, which I've been eating for months, but it seems my last reaction left me more hypersensitve so I'm back having all the pain and stuff I was having before.
We did figure out what originally set all this off, I had been a whole bunch of Cinnamon Toast Crunch over several days, and once all of this started I looked at the ingredients, and it turns out it has both dextrose and fructose fairly high in the list. I'm pretty sure they didn't use to be in there, I ate it because I had thought it was one of the only cereals I could find without any corn. So I will be staying very far away from it from now on. I really wish they would put a warning on the box somewhere when they change ingredients like that, so I know if I need to stop eating it.
