They changed the formulation of anti-freeze a few yrs back & substituted the proplylene glycol with something suposedly non-toxic to pets & she seems to have reason to believe her neighbor would have the tendency to do something like this. Should the toxicology report identity the poison & it seems intentional, then I'm in favor of non- lethal revenge. A little laxative never hurt anybody, & a good cleaning out might clean up his attitude. Puts a whole new meaning to the phrase,' scared the shit out of him'. But I'd wait for the vets verdict. No use starting world war lll in your neighborhood if you're wrong. I feel when someone does something mean to an animal, it should be done back to them.
