Poor Sweetpea! This can be a common problem in cats. It can be cause by stress, a bladder infection, urinary crystals, kidney infections and/or bladder stones. I would her looked at by your vet to ensure she doesn't have an infection and that her kidney values look okay. Your vet will be able to run an urinalysis and blood work to assess these things. Since this is such a common problem, I would have bladder stones rule out as well if this hasn't already been done. Finally, since this is a reoccurring problem, I would also consider switching Sweetpea to a prescription urinary diet like Science Diet C/D stress to help decrease the number of flareups she has in a years time. You can also add cosequin for cats, a joint supplement, to her diet. One of the side effects of cosequin is to increase the mucus in the lining of the bladder which will ultimately help to protect the bladder wall. I hope this helps!

    Thanks for using Petco Pet Education Center, formerly Petcoach! I’m sorry to hear Sweetpea is having urinary issues. Blood in the urine can have multiple causes, including an infection, bladder stones/debris, stress, or an underlying medical issue (such as diabetes). I would recommend she be evaluated by her regular veterinarian, have any necessary testing done (urinalysis, bloodwork, X-ray) to determine the underlying cause for what you are seeing, and start any treatment that she may need. Good luck!
