Current carrying capacity of CAT5?

Just completed my pair of water leak detectors for under the washing
machine and dishwasher, loads of coloured LEDs, ooh er missus.  I plan
to feed them with power via the CAT5 cabling, which will also carry a
copy of the status LEDs back to the central indicator panel.  Anyone
know what current can be safely poked down the CAT5 cabling?  The major
current is drawn by the water shut off valves, which are rated at 12
volts and 3 watts, by my rusty maths thats 0.25 amps each, and the
washing machine has a pair of valves, so 0.5 amps.  Are my lovely
coloured lights going to be invisible through a cloud of acrid smoke?
