Not too much longer

So I was chatting with my vet yesterday after another brief episode of behaviour change.  I fed my lady on Wednesday (I think) and after her dinner, she came out of the room that I feed her and just wandered.  She was looking all over the place like she was lost, like she had no clue about where she was, or who I was.  She puttered around the main floor for about 5 minutes like this.  I didn't intervene as I thought I'd just wait and see how long it lasted.  I started doing the dishes and that seemed to have been what brought her out of her episode.  She has a bit of OCD now and she needed to be on the counter, licking the flavoured water out of the dishes on the counter before I washed them.  I spoke to the vet the next day, and she suspects it is the meningioma (not surprised).  I asked what Dock's max dose of Prednisone is, so I can increase as needed.  Also to get an idea of how much longer I'll have her.  Looking up the dose, my vet said that she is already at her max maintenance dose.  We can increase it temporarily, but for only 5-7 days.  Right now, she is not acting oddly enough, consistently enough for me to do that.  I'm going to see how she does, then increase when I feel she needs it.  One good thing though is my vet does not believe she is in pain.  If she was, I would increase her meds, then look at the hard choices this week.  But right now, she seems happy, and that is all that matters to me.
