So my 8 year old female cat started meowing loudly a little while ago. I went downstairs to clean out her litter box and discovered she peed on the floor and the urine was bloody. She's never had any health problems and I'm freaking out about this right now. Has anyone had a similar experience with a cat? I made an appt for the vet for Monday but am wondering if I should take her to the 24/7 emergency clinic.
