My 10 month old male guinea pig had his first stroke, 12/3. Then seemed that another one occurred a week later. Resorted to hand feeding but he seemed to have another one during the night. Died unfortunately what may have been a cause? Had been seen by vet and placed on cipro and antiinflammatory. As he had head tilt, nystagmus, and balance issues. But ears appeared fine and symptoms occurred suddenly.
