<human>: Can you give me a shortened version of the text?

I signed a lease in August and have been living in an apartment with three roommates since. Since I have started living here my roommates have adopted 2 cats. Putting aside the facts that: I do not care for cats, I have slight allergies to cats, and the cats have fleas which have been been biting the ever loving shit out of me leaving misquito-esque bites all over me; I have tried to be as "cool" of a roommate as possible about all of this.   
  
At the time you sign your lease or throughout the term of your lease you are **supposed** to pay a deposit here for any animals you intend to have living with you. My roommates have neglected to take advantage of this. And of course, now all our furniture (Leather) is beginning to show signs that cats live here. It could be worse, but this is where my problems begin.  
  
As I have to live here throughout July, I want to know how I can approach this situation to absolve myself of all financial responsibility when our lease ends and they come seeking compensation for the damages that have accrued throughout our stay here.  
  
Basically, I want to know if I can write up some form of contract to have them sign which waives me off all liability, and if I do so, if our apartment complex would have to honor that agreement when we move out.
<bot>: My roommates got cats without paying a deposit and now they are beginning to tear all of our shit up. HOW DO I AVOID PAYING FINES FOR CATS THAT DO NOT BELONG TO ME?
