A random guy messaged me on facebook. What should I do?

I got a random friendship request from a guy on facebook. I ignored it, but after a few days he messaged me 'Hey'. I replied with '.. hi?' After that he sends me 'I just saw you on facebook and i think you are really cute'
I haven't replied yet and I also have no idea if I even should reply. I have never seen this dude in my life but... I don't know :/ It's not like I have any interest in him because i like someone else, but he does seem really nice..

by the way I'm reaally bored so I added a poll about what you would do if you were a cat for a day:D So if i were a cat for a day, i would...
Eat catfood all day
Pester humans by knocking over all of their stuff
Climb in every closet and cabinet of the house
Stalk birds
Eat birds
Play poker with the neighbours dog
Yell at the tv for not being able to turn it on

'""UPDATE"""I just said 'Thanks but i dont know who you are so kinda creepy...' Then he said 'You really are cute' I said 'uhh.. thanks' He said 'Np' and i didn't say anything after that at all and neither did he. I see a lot of reactions saying don't meet up with him and all, but I wasn't planning to. Just wanted to clear that up:) Thanks for all the reactions though! never got this many:^)
