i used to when i was in like grade7/8 people dont give their animals enough credit, once theyve been around u while yer blazing a bit they kno, what it is weather or not they like it. this girl i kno has a cat that will sense when were blazing and come hauling into the room as fast as she can and sit above us sniffing up all the smoke she can. my cat? runs like theres a demon chasing her as soon as she hears the bong noise. if yer animal alsways comesa round when yer blazing then by all means get it high, thats prolly what it wants, but dont force it. in highschool some kids used to do that to my buddy johns rat, the poor thing got cancer and started seazuring(sp?) and eventually died.
