My 14 yr old cat suddenly went blind last week. We took her to the vet immediately and they determined her retinas had detached. Their tests showed her kidneys and thyroid are fine, and then an ultrasound showed she doesn't have any heart disease. The walls of her heart are thicker than normal and she has a heart murmur though. Basically all they found is she has extremely high blood pressure and hypertension but no other underlying disease. They've put her on blood pressure medication twice a day, Amlodipine. Since the vet, she has not eaten or drank at all being at home. We brought her back to the vet and she spent three days there with them giving her fluids and they managed to get her to eat dry food with appetite stimulants. Now she's back home since Wednesday and is back to not eating or drinking. She has started doing a weird thing with her tongue. It's like her tongue is uncomfortable in her mouth. She's licking her lips and her tongue is almost always sticking out quite prominently. We showed the vet and she said it was weird but couldn't see any swelling or sores. We managed to entice her to eat some wet food today and it seemed like she couldn't eat properly. She licks the food but can't scoop the actual pieces into her mouth. I'm at a loss for what to do next. The vet really isn't offering any other solutions. I'm coming to this forum looking to see if anyone has had a similar experience or has any advice. She's become completely listless and just lays in a bed all day. I have to find something to help her. Any help would be very appreciated.
