We are going through a stressful time with our sweet 13 year old, Rudy. About 2 weeks ago we took Rudy to the vet. I had noticed his belly had become very large and hard. We thought he was constipated. I didn’t know. Well, there turned out to be a large amount of fluid in his abdomen. After bool tests and a week long of ultrasounds, xrays and tests, he was determined to have failure in the right side of his heart, and the vet said this was causing the fluid. He was put on Lasix, a diuretic, and Benazepril. Rudy just isn’t himself. He is not purring, he is not at all his usual self. The fluid has only gone down so much, and then sort of stopped. It has decreased his waist measurement by 1 3/4 inch, but it fluctuates still. My sister nd husband believe he is recovering and it will take time and he’s in good hands. I just get so much anxiety and am worried about him. Does anyone else have experience with this and can offer any thoughts? Like, did your cat experience this and how long did recovery take? Did they get better or worsen right Away? Any help would be so appreciated! I just love my fella and this is so hard to see him so listless.
