It isn't an allergy so much as it is the fact that bacteria grow like
crazy on plastic dishes - therefore it is an infection and your little
one probably needs antibiotics and new, nonplastic dishes.

I was the one that posted about the swelling on my cats bottom lip and
chin. It was suggested it might be an allergy to his plastic dishes or
food. Wouldn't such allergies cause itching though? Still trying to
figure out what's going on with him. I'm not encouraged about reading
about vets not helping and giving things that might harm cats such as
cortisone shots.
