A 1-year-old sexually intact female Brazilian Shorthair cat was evaluated because of bilateral third eyelid protrusion and tremor episodes that had started 4 days earlier. According to the owner, the cat had had 1 episode of diarrhea that had resolved spontaneously. The 4 other cats that lived with the patient were healthy.
During physical and neurologic examinations, a low body condition score (3/9), dehydration (7%), moderate bilateral third eyelid protrusion, and neurologic deficits consistent with lumbosacral myelopathy were observed. According to the owner, signs of paraplegia and urinary incontinence had been present since the cat had been adopted.
The authors thank the Brazilian Ministry of Education for providing a scholarship for a veterinary medicine residency, which allowed the presentation of this case.
The authors declare that there were no conflicts of interest.
