My multiple handicapped little Thumbelina had pyometra some years back, but luckily I knew the symptoms, and she was rushed into the vets on a Sunday and spayed. It was a miracle she made it through (not from the pyo) but she has megaesophagus, a severe heart murmer, and radial hypoplasia all packaged into a very tiny body. The tube they put down her throat really messed her up for a few weeks, but in time all was well again. The best part was the vet charged me $00.00! He's got a soft spot for special needs kitties. I'm glad you got Gidget in to be looked at. I hope they have her on antibiotics and fluids while she's in, to keep the infection down. And open pyo is much better than closed (infection is able to drain with open). Keep us posted. Hope all goes well with her surgery. Jan
