Lens will not extend

Question

I opened up my camera because, well, my cat peed on it indirectly and the shutters wouldnt close properly however the camera still functioned fine. I opened it to wipe the remains of urine from the shutters so they might close. They close decently enough however now the lens will not extend. It makes a noise like it will then the message "Turn the power off and on again" just reappears over and over. I don't want to take it to a repair shop just because I opened the camera to clean the shutters. How can I fix this problem without having to spend money to have it fixed?
