[QUOTE=SatanicIntention]Flagyl isn't a tube, it is an antiprotozoan(anthelmintic, dewormer, etc). Your snake probably had Giardia or Coccidia and that was what contributed to the bloody diarrhea/feces, and not the piece of bedding.
Well my vet must of lied then.. he said the liquid they put in their stomach is done via a tiny tube & he also said it must of been the substrate that was causing the bleeding...
