My cat Atreyu had surgery almost 2 weeks ago to remove bladder stones. She has been acting much more lively and I can tell she is feeling better, but I noticed today there is still a bit of blood in her urine, and she still won't per in the litter box. Just wondering if it's normal for blood to still be present since there was an incision in her bladder, or should I be getting her looked at again? I plan to call the vet Monday, but I'm worried there's something wrong still.
