She ate well and took her meds, by syringe without being toweled.
I think that is the right thing to do. I wish you can continue doing so.
I would have done anything that not was making her stressful.
Have you been discussing if she can have epilepsy?
If they get a seizure they get unconscious and are unreachable. When they wake up they are very confused and don't recognize their owners.
I'm not sure that you should hold her when she have a seizure for that reason. Can't you place her in a darker smaller area with no sound, and see what happens?
And let her stay until she recognize you or your wife.
Have you have her tested for lead poisoning?
I think you should try something, and I still think that the trigger is stress.
If nothing helps, and she's not getting better, you always have that last sad option.
You will know what to do and when. But until then I continue to sending positive and healing thoughts her way.
