How do I repair my MacBook Pro case?

Hi everyone !

Yesterday my dearest cat made my macbook pro fall from about a 4-5 feet height .. The pc was inside the case so there were no visible marks or scratches ( plus it fell on a very thick carpet ) .. I didnt notice any problem with the case until i put the pc on the desk and noticed that the case was bent ... The upper part ( the display ) will not close completly on the right external corner ( remains open of about 2 mm ).. And on the same side , the bottom part bents upwards ..

Now ive been reading that its possible to straighten it using specific tools ...

Is that true ? And if so , what do i need ? And how do i do it ?

Thanx in advance and excuse the english ( not an english native )
