My cat is fourteen years old and I had her fixed when she was old enough. She has never had kittens. We recently moved and that's when I noticed the blood in her urine. I thought it was cuz of the move. Well it went away for a few days and now it's back. it dosen't happen every time she goes but when it does it's bright red. She is also an indoor cat. Thank you for listening. Liz.
It sounds like your pet may have a urinary tract infection and should see a vet. Stress can contribute to this. vetcare
