I have seen MANY dogs and cats have owners "get them high"... (I was a bit of a party animal in my younger days, teenage). I have never once seen an animal "freak out" like it was paranoid, or having a bad experience. They all just got mellow, or cats start playing with invisible things.. marijuana tends to enhance the mood your in... I am not saying it is a good thing, just reporting what I personally have seen. No idea about how it affects different species...
I do know hard drugs are bad for cats...
I stole a cat from a drug house once. It had been fed LSD, and probably alot of other things... walked sideways, and would try to jump on things and miss, do headplants into everything constantly, which is why the junkies loved the cat... it was **** amusing when they were high.
I kept him for a year...then this little girl just fell in love with him. I didn't know who she was....hung out by my house when her parents were working. She was about 9. She wanted him so bad, I finally met her parents... she turned out to be from a very wealthy family, I talked to her parents, they wanted to adopt the cat.... that cat went to the lap of luxury
Anyway.... ROFL! Marijuana needs more research in regards of medicine for ppl and other species.. it got demonized, and could b useful....
