Can cats get a contact high from marijuana smoke? If yes, how is this?
How about other pets or animals?

I know from personal experience that pot smoking, binge drinking, and
other recreational drugs are not good for kitty cats or goats. My poor
goat didn't deal well with the party life (may poor Billy rest in
peace) and I know of a perfectly good kitten that didn't fare any
better either. I lived through it, but not without serious scars.
Animals deserve a better life.

Yep, cats get stoned. Dogs can get drunk, too. I refuse to elaborate
on how I know this except to say I had strange friends.

Hmph, odd thing is I still know them well and cannot wait until their
kids hit puberty...
