Peaches needs to see the veterinarian quickly. It sounds like this may be neurological and this is never normal. It can indicate many things including toxin ingestion, drug exposure, an infection in the brain, brain cancer, drug exposure, low blood sugar and other sinister reasons. A physical exam and bloodwork are needed to begin figuring out the cause and the best treatment. Other diagnostics may also be indicated. I hope it's nothing too serious and that she gets back to normal quickly.
