A few hours ago we found her huddled on the porch couch. We are almost positive she was bitten by a rattler. Shes very listless. She was coughing blood but just a tiny bit and that was hours ago. She breathes like a child w/ a head cold. Im sure this sac is filled w/ a not-so-good, but have no idea how to deal w/ it. Were trying to remain calm. Any help would be appreciated by Zsa Zsa.
