Thanks for using Petco Pet Education Center, formerly Petcoach. I'm so sorry this happened to Smeagol! The blood and mucous or mineral material you describe are common for blocked cats. Usually the catheter remains in place until the urine is a normal yellow color. Usually 3-4 days is sufficient. Ideally, Smeagol will also get antibiotics to prevent an infection from the catheter and medications for pain and urethral spasm. I recommend calling or visiting your vet if you have further questions. Best wishes to you and Smeagol!
