Thirmerosal was an ingredient in the rabies vaccine that was administered to my INDOOR cat against my wishes. (State law in soviet Red Hampshire...rot in hell.) He died from ‘cancer’. I will never forgive those bastards.
Thermistor did not kill your cat.
Neurotoxins affect smaller animals more than they do larger animals. I did a whole study in grad school on metabolism and the animal’s size. Vaccines have the potential to cause more harm to a dog or cat than a human.
