What does it mean?
1) Exactly what "damage range" can it have? Because (1d3–4) translates into "from -3 to -1". Negative damage???
2) What can I apply "+4" to ?
As per the SRD: "Damage from an attack is always at least 1 point, even if a subtraction from a die roll reduces the result to 0 or lower." So a rat only does 1 hp damage unless it's enhanced somehow.
The +4 applies to the attack roll. Roll 1d20+4 to hit.

Because a rat with Bull's Strength and Prayer active would do 1d3-1 damage (1-2).
A rat with Bull's Strength, prayer, and bardsong active would do 1-3 damage.
Ya... I fight those rats all the time. They're such a pain . Friggin' evil rat cleric bards. Fortunately I can heal up between battles by letting normal rats bite me a lot.
There's also crits, where the rat might get a whopping 2 damage! Or if you're like me and want to add some fear to your average encounter add a druish were-rat capable of boosting it's horde... hehehe.
