I honestly wouldnt do it to my animals. Just because i dont think there lungs would process it very well.... and i wouldnt want to hurt my cats respitory system. Or make him go into reefer madness. If they do not have the ability to say yes then i dont think we should make the decision for them. I love my pet more then i love getting a laugh at there expense... soo overall its your call wouldnt hold it against you but.. i personally wouldnt do it.
