My cat ate the white part of white out tape

My uncle told me she just chewed on it so I dont think she was able to eat any of the physical tape, but I think she ingested some of the white out. Im from Canada, and I called my vet, the emergency vet, and animal control. None of them can tell me if white out is going to kill my cat. Please help! She seems okay so far, just vomited some white foam.
