Although there are some feline viral diseases that would typically be present in litter mates and can cause neurologic disease, I would suspect that you would have noticed that one or both cats were sick prior to this if that were the case. In a 2 year old cat the most likely cause of seizures is a toxin exposure, so I would be sure to check the area very thoroughly for any potential hazards, such as antifreeze, that may have precipitated this.
