Did something in my roof disrupt the electricity?

My neighborhood has been having squirrel problems for a long time now. Everytime we set up cages or glue traps or sit outside and shoot them, they always end up coming back. My room is in the corner of the hhouse, say, the bottom left corner if you think of it from above. Its also upstairs. I can hear a lot of sniffling and scratching. Well today i was on the pc playing minecraft when i heard the noise again. I alerted my dad and he came in to listen to it. Then my pc turned off suddenly. I can't turn on my lamp either so all of the electricity in my room went out. Not to mention that my sister's room, in the bottom right corner, power also went out there. Everywhere else in my house is fine.

Also my father said that it didn't sound like a squirrel. Anyway, do you think that the animal did something? Should we check the attic? Where in the world could the animal even touch electric cords from the roof/vents?

It is possible the squirrel had chewed through some wires running in the ceiling cavity. The sound you may have heard could also have been arcing which might have sounded like scratching. Check your circuit breakers as they may have tripped do to a fault caused by an animal, if they have call an electrician to have a look.

Go look. Arcing wires can cause fires. Mice eat wires all the time. Trun off that circuit at the breaker first, then either check yourself, or call some one.

Depends on the wiring, sure. You shouldn't run lines through the attic, but some might.
