My cat 'Bud' used to love ganja smoke (way back in the day). His eyes would dilate like mad, he'd get a mischievous look on his face, and then he'd chase butterflies and birds around the yard. After about an hour of that, he'd eat like a horse (he especially liked to lick a scoop of vanilla ice cream), and then he'd pass out for at least 18 hours.
....and he lived 23 years.
My cat behaved like that all the time. I wonder if he was getting high. This in a house without ganja or tobacco smoke. How's dat fur science?
