I'm starting to wonder if my cat Marvin might have the issue with Cushing's disease. Something that has been bothering me a lot is that recently he has become much more skiddish. He spends nearly all of his time now in the basement under the bed in the guest bedroom. Once in a while he'll come upstairs, but he acts disoriented and fearful. And when he sees me, sometimes he just give me a fearful look and run. It breaks my heart. He didn't use to be like this. I thought that maybe it was the insulin and all the testing and shots, but he actually takes all that pretty well - in stride. Poor guy. I'm not sure what to do next. I'm wondering if I should have him tested for Cushing's, if there is a way to test.
