Salivation: Uncontrollable watering or foaming of the mouth.
Lachrymation: Teary or watering eyes.

Some or all of these symptoms combined with atypical pupil

Typical treatment involves decontamination or poison control
as soon as is practical, coupled with atropine and/or oxime injections.
All of the above flashed through my head when my cat suddenly

application of some off-brand flea medicine. He had to be rushed to the vet, bathed,
and treated. I'm very grateful my dad taught me this.
