Now that the infection has cleared up, I would plan to spay. Directly from a publicly available vet hospital website: “The rate of recurrence of the disease in a treated cat is generally thought to be as high as 50-75%.”
I honestly wouldn’t risk the queen.
A veterinarian should really check out the cat’s unusual behavior. The doctor would need to determine if there is an injury which would determine the course of care. I wouldn’t delay seeing a vet as the cat may in pain. Best of luck, I hope the kitty is acting better soon!
I would worry about trauma to the spine or head. Please encourage them to get her in ASAP.
