Plain-English summary
A 6-month-old male Ragdoll cat was brought in with severe episodes of methemoglobinemia, a condition where the blood can't carry oxygen properly. The veterinarian treated him with an intravenous infusion of methylene blue, followed by oral doses of the same medication. Thankfully, the cat made a full recovery and showed no significant side effects from the treatment. At a follow-up six months later, he was healthy and had not experienced any further episodes.

Abstract
OBJECTIVE: To describe the use of IV infusion followed by oral administration of methylene blue (MB) to successfully treat recurrent methemoglobinemia (MetHb) in a young cat. CASE SUMMARY: A 6-month-old male Ragdoll cat presented with recurrent episodes of severe MetHb and was successfully managed with IV infusion of MB followed by a course of oral MB. Although the definitive cause of the patient's MetHb remains unknown, the cat made a full recovery following treatment without developing any significant side effects secondary to therapy and at the time of writing not had any further recurrences. Follow-up at 6 months found the patient in good health and without any long-term consequences. NEW INFORMATION PROVIDED: To the authors' knowledge, this is the first report of a cat presented with severe MetHb quantitatively assessed via co-oximetry and successfully treated with both IV and oral administration of MB.
