Usually, when I lose a Guinea Pig, I understand why. Guinea Pig diagnostics are tough, they don’t show any sign of illness until they drop dead. Symptoms of upper respitory infection, like discharge from eyes or nose, weight loss, lethargy, only show up once the pig is beyond hope.
She was bouncing around eating yesterday, and playing the wooden toy. Her eyes are clear, with no signs of discharge from that or the nose. The cage was clean… She had not lost any weight, in fact she was up.
She must have gotten ahold of a toxic plant? Now identify which one… But the internet guy won’t get here for me to do some research on what until later today, and I am out if data.
