I’m sorry to hear that CJ is not getting better. At this time, since she has not responded to traditional therapy I think you need to pursue further diagnostics like blood work (to rule out hyperthyroidism, diabetes and kidney disease), X-rays (to rule out a mass or blockage) and possibly an abdominal ultrasound. Also, you may want to consider talking with your vet about hospitalizing CJ with IV fluids and medications until she is stabilized and you can determine what is causing her illness. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. If you have any more questions about CJ or her condition please let us know!
