My 16-1/2 year old calico has been on prednolisone since August. Even though she was still eating normally she went from about 9 pounds to 7.2 pounds in a year. Tests showed everything was good with the exception of inflamed intestines. Being on the prednolisone has helped her gain weight again, she now weighs about 8.4 pounds. Within the past month on occasion she has started howling very loudly for no apparent reason. She doesn’t seem to be in any pain, sometimes it actually seems as though she’s confused. Any ideas on what could be causing her howls? What can I do to help her? Dr Graff has been her vet since she was a tiny kitten, I would bring Pumpkin in if necessary but hate the idea of stressing her out in doing so. Thanks for any suggestions.
