Good news!
We just got home from the vet, and Nikki's retinas appear to be reattaching. The vet said that she totally expects her to regain her sight. I cannot believe it! I am so happy.
Also, Nikki's blood pressure dropped from the horrible 240 on Thursday to 180 today....which is still high, but much better. We are doubling her dose of amlodipine, and she has another appt next Saturday for a recheck.
