Searching for a Flatshare (cats allowed)

I'm an electronic engineer, I'm 28 years old, I have a good sense of humor. I like to play the piano, I like sports and I like pizza and I like to cook too.
I'm looking for a Flatshare during my MSc in photonics(planning to arrive on mid September), I like to meet people from all over the world. I'm not a full time geek who won't come out of his room. I like to have good conversations and occasionally some beers with friends. I have a cat that has become my partner since 2010, and I hope to find a place where we both can live. (She also likes to walk in the park with a chain/necklace like a dog).
I've never been in Germany. My aunt lives in Blieskastel but is quite far away from Jena.
Do you want to know how does it taste the Colombian Cousine? Do you want to laugh about anything? Do you like cats? Do you have an available room? If so.. I'm your man!
