Not so much what I learned TODAY, but yesterday. Hubby and I thought one of our cats had kidney cancer. We'd been worrying about it for the past few weeks after an x-ray indicated we might be looking at cancer. We finally learned yesterday from an ultrasound (from a radiologist that was brought in from another vet) that it is not. A bunch of kidney stones is all it is. She has been bleeding consistently, so she has had 5 vet visits in the past month or so, so it was worrisome. It was feeling like deja-vu after our cat having end-stage cancer last year. Anxiety level way down today now!
