yah. first off lets forget about just how cruel it would be, how would you ever get a cat to eat shrooms to begin with? plus, did i mention it was cruel? idk why people who enjoy recreational drugs think that their pets would also enjoy them? i don't get it.. what on earth kind of enjoyment would a cat get out of trippin on shrooms? i bet if it didn't kill the cat, which i dont think it would, it surely would fuck that cat up for life.. not a good idea.. leave the drugs to things who are able to make a choice as to whether or not they want to do them.. i would be pissed if someone slipped me some lsd or shrooms and i wasn't told ahead of time, and i enjoy tripping..
