Um I have this relatively cheap green laser that I want to format to be more powerful. Yet I want to be able to adjust it so that I can use it to mess with my two adorable cats whose eyes are as precious as they are. I have no idea what the wattage is, the sticker came off. I bought it in the Monasteriki square in Athens, Greece, where there are street vendors galore. There wasn't a sticker mentioning the wattage. it was probably a 1mw. All i know is that it is 550nm. So can anyone tell me how i can format it?

It is definitely not 550 nm, not unless it uses some expensive technology not ordinarily found in laser pointers. It is almost certainly 532 nm.
Twiddling the pots inside your laser pointer is bad, as it will almost certainly blow the diode.
If you want to try anyway, there should be a small potentiometer on the driver board that you can replace with an external adjustment knob.

cheap 1mW green lasers can have much higher spikes in power
I would be careful with the cat's eyes....or yours for that matter.
