Noticed this morning that Ollie had done a very bloody wee. Aside from this, he seems completely normal in himself, eating, drinking, playing etc. I am taking him to the vets first thing in the morning but just wondered if anyone had come across this before? He had cystitis about 3 years ago, which was treated successfully. Last year, he went through a phase where his pee was very dark for a few days, once with blood in. Again, he still seemed himself. That time, the vet could find absolutely nothing wrong, after many many tests. I am hoping it will be the same result this time, but surely something must be up?
