1. Get an epileptic cat.
2. Leave him alone (well, with his adopted sister, who hates him, to babysit) and without medication while you go to work in another state for two days.
3. Watch him have a massive seizure when you walk in the door at 11 p.m.
4. Enjoy excessive cuddling, purring, rubbing, and plaintive cries which can only be interpreted as, "Don't ever leave me again!" for the rest of the night.
