These are pretty interesting http://animals.howstuffworks.com/pets/pet-travel/6-pets-that-traveled-long-distances-to-get-home.htm
the first time i dropped lsd i hugged my dogs...but nothing unusual...they always seem to look at me like i'm out there.
I've noticed this too. Last time I was on acid, my canine companion barely ever came within ten feet of me. Must've been pretty wierd for him, I mean imgaine something trippin guy with a huge grin on his face and completely dilated pupils calling your name.
i think i may have only tripped around a pet once. and it wasn't even mine. it was my GF's friend's cat. we were all tripping on L and her black cat was making me pet it. you know how cats do that, like rub themselves up on you. but it seemed to me that the cat was way too into it, like....sexually? it was a bit weird for awhile, but i shook it off - chalked it up to tripping.
