oh wow great find phred!

upon reading it does say to avoid inhalation of vapors or mist and to avoid contact with clothing. also says under inhalation: "exposure to high concentrations" can cause drowsiness or drunkenness.

so.. maybe that was it, but Id only think so if it was still damp or was recently saturated. otherwise I imagine it had had plenty of time to air out.

gotta keep in mind those warnings are basically for mis-use/over dosage. though since the product wasnt made for use in animals the effects could certainally be much different.
