Ruffles blood work all came back fine! The vet said the kidney function looked excellent, and nothing like she expected for a cat this age! So no new meds, no changes to meds.

It is possible the heart murmur (which the vet calls heart disease) could be causing problems. We could also do an ultra sound of hr abdomen to see if anything shows up. but her white blood cell count is normal, so the vet isn't sure that is an issue.

We are continuing the high calorie foods. She is enjoying them and eating much better. Could all this weight loss be because she can't eat hard kibble any more??? Then I feel badly, that means she was starving!

So in 2 to 3 weeks I will take her in to get weighed and either make another appt with the vet or leave a message with the front desk to tell her the weight is coming back on.

Thanks everyone, I believe PT prayers helped!!
