As strange as it may appear, cats may get seizures if they hear certain types of high-pitched sounds. Common seizure triggers were crinkling tinfoil, hitting a ceramic bowl with a metal spoon and tapping glass.

The Journal of Feline Medicine and Surgery looked at data from 96 cats including the type of seizure, how long it lasted and what sound appeared to trigger it. They found that some cats suffer from seizures caused by sound, known as “audiogenic reflex seizures” that could trigger brief muscle jerks or even cause the animal to lose consciousness.
