i've never witnessed it, but ive gone in there and had older hammies who've had strokes, ive also had 2 mice have strokes whichrecovered aswell as two hamsters, but usually you cant do much for them, if they are quite bad, if mine have had a stroke/heart attack they have a warm teaspoon of porridge/oatmeal with a small amout of sugar which will increase their energy levels...
