I too feed my dog purina dry food for "indoor dogs".
I didn't see it on the list buy I will take it out the minute that list changes.
My dog craps all over the place when we feed her wet food so we have only done it once. She does like peanut butter though.
I think some of the dogs affected are dying of kidney failure so if you dog has signs of kidney problems (don't know what they would be) then get it to a vet.
I dont know/care about the cats.
