The cat do not know, while her last 90 seconds. Thank you for your cares about the poor kitten! Maybe you can give her epilyptic-pills soon, to avoid broken bones and joints.
Cat's seizures give me an imperssion that seizure might be a situation where brain trying to do multiple action that is contradictory, at same time, like this one here looks like trying to walk, groom, hunt, fight and eat at same time Perhaps's brain's function is desynchronized and every part of brain is firing its own command to muscles.
