Remember the washcloth full of catnip tea? I stupidly left it on the floor of my office for Sekhmet to enjoy. You know, trying to be nice.
She ate the catnip.
So she passed out, and was sleeping, curled in a ball, twitching and rowfing in her sleep. (She does this normally, but this was bordering on convulsions, not the usual mild twitchies.) So as I usually do when she's dreaming, I laid my hand on her back to wake her up.
She SCREAMED, lept straight up in the air hissing, and landed facing the other direction - toward me (who at this point had also jumped and shrieked and was thinking of hissing), nearly throwing herself off the futon. She puffed up to twice her normal size, sort of blinked, got her bearings, then began meowing pitifully ("meow? meow?") and crawled into my lap, purring at me for reassurance. I petted her for a while until she chilled out.
Damn stoner cat. Fucker's going to be stuck to me all night, probably hallucinating.
