Blimey, quite surprised you caught the little beggar :lol: A mouse got into my folks house once and it was a nimble little thing. Took a while to catch it - used a small plastic bucket and slid some card underneath after I managed to trap it.
You want to make sure you get a tetanus jab (depending on how long since you had one) if the thing bit you. Eihter way, probably best to see your doc to be on the safe side - there's plenty of things a wild rodent could be carrying.
