Words fail me.

How very odd. The guy getting the cat to say 'i love you' was the scariest of the batch though.

My ex's cat used to try to emulate bird noises in order to try and get them to come closer. Failed miserably, but didn't stop her from trying.

My friends cats are nicknamed Fat and Less Fat (who isn't very fat) and they sit in the bushes maknig bird sounds sometimes and POUNCE! for the kill.

This video sounds fake to me though, those are very human like noises.
