Can confirm, patting a cat while high as fuck on opium will make the high better, maybe not double, but definitely fully enhance the situation, just like being on MDMA or cocain and hanging out with a dog does the same.
Meth is made better with a bird, specifically one that loves screaming back at you.
Acid is made better by fish in a fish tank or pond.



Now, imagine you have a cool dog with you on your methventure.
