Just got off the phone w/Dr. Lee and he feels that, indeed, Coco Puff's hearing has been affected. He said that it's common in cats w/sinusitis and Coco had a really bad bout of it. I'm to start him on Prednisolone again, only this time he wants me to give him a full caplet twice a day for 5 days, then to back him off to every other day. He also said that the confusion that Coco had was more than likely due to vestibular build up, i.e., what used to come out of his nose when he sneezed is now backed up in his ear canal. The Pred should bring down the inflammation, allowing the blockage to loosen. If I don't see a positive change in 3 days, Coco needs an x-ray of his skull to be sure there's no tumor there. Sigh. Please keep your prayers up for my little Raoul Boop.
