You're absolutely right about PG and cats Crash, except you can't blow enough in their faces to make them sick. I just happen to have this info at hand because it came up last night.
The issue with cats and
vaping is that if they
ingest a large amount of PG it is bad for them.
See here for the low down. PG is not used in any cat food.
In a nutshell, if your cat drinks juice it will be bad. If your cat vapes, it's all good
This affects no other animals.
