I do the same as the other posters, take one (or more) to the vet, and then come back and feed the rest. If I have to rush to work directly from the vet, I prep everthing to the point of opening cans, pop the vet-bound cat into carrier and car, then run back in and put out the wet food. I wouldn't isolate because that's like a double strike against you in her eyes. Good luck!
