My cat's urine was red, now it's normal. Does she need a vet?

Pet's info: Cat | Mixed Breed | Female | spayed | 16 years and 3 months old | 7 lbs

My cat had red/brown urine on Thursday night so I watched her Friday and Saturday and her urine was a normal yellow color and still is. Should I take her to a vet still? (She had been having trouble pooping but she was able to this morning)

I would recommend that you have Misty seen by a veterinarian. It is possible that the off-colored urine the one time was caused by dehydration, but there is never an ok cause for having blood in the urine, especially since she is an old cat. Possible causes for discoloration in urine include UTI, urinary bladder stones, feline interstitial cystitis, cancer, or other systemic disease like kidney or liver disease. Discomfort during a bowel movement can indicated constipation, painful bladder (as noted above), or arthritis. These things could be easily diagnosed and treated by a vet.
