Hi, everyone. My furry daughter Emma is diabetic and has been on 2 1/2 units of ProZinc in the AM and PM for over 6 months. Two weeks ago, she was diagnosed with high blood pressure when I started noticing that she was very careful about jumping up and down the couch and chairs and her pupils were always pretty dilated. After a visit with my local vet, he had me go to a veterniary optamologist who diagnosed bilateral retinal detachments. She prescribed .625mg of norvasc(amlodopine) and scripted out a bunch of tests to have my local vet run on my cat. Eye vet said that normally cats with high blood pressure have an underlying issue such as hyperthyroid or kidney disease. My local vet ran all the tests and blood work and everything came back normal. The blood pressure meds are definitely working because the eye vet was confident that once the blood pressure went down, that there was a good change the retinas would reattach as I caught it early. Sure enough one week after I started the blood pressure meds, her eyes look much better...she can follow my fingers, see the birds outside, and jumps out and down like normal. Only problem I have now is, she is drinking a lot of water which means she is peeing a lot. Local vet checked her blood sugar and he says it's normal. He is thinking it's the blood pressure meds but I have seen nothing online that says norvasc/amlodopine side effects is increased thirst and urination. So I am totally stumped as is my local vet. Has anyone ever experienced anything like this? Could it be the blood pressure meds? Emma has an eye doc visit tomorrow as a follow up and I am having Emma's blood sugar tested at the locat vets again on Thursday afternoon. Other than drinking and peeing a lot more than usual, she is acting normal. Any comments/suggestions are greatly appreciated!
