Help My Cats Stay in Their Home

My name is Cassie Conlin, and I am the proud adoptive mother of Brutus (left) and Lil Caesar (right).  
I have been informed by my landlord that I must pay a non-refundable, one time fee of $600 (that's one $300 deposit per pet) to cover any possible damage to the apartment, regardless of whether or not the cats have actually caused any damage.  I have only one week to either come up with the money or remove my cats from the property. If I fail to do either of those things, I will promptly receive $600 in fines, followed by an eviction notice.  I'm in my fourth year of college, and after a bike accident, a root canal, tuition payments, rent, food, and kitty litter, I have not been able to save up a single dime to go towards paying this deposit.  I already paid my landlord a security deposit of $400, but they insist that is not enough and no amount of pleading will make them change their policy.  My cats helped me to quit smoking cigarettes, and I pay only $10 a month for my phone bill.  I haven't bought a textbook in 3 years, I just rent them from the library. I've been going to food banks to ask for emergency meals and non-perishable food items.  I cut down on every single cost that I possibly can to ensure that I always have enough money to purchase cat food and cat litter, as well as the charcoal filters needed to keep their water fountain clean.  
My cats and I would greatly appreciate any donation that brings us closer to being able to pay the pet deposits for my apartment.  Any money exceeding the $600 needed will go towards paying for their food, litter, and check-ups from the vet.  

Brutus, pictured above.  Birthdate: August 1st, 2013.
I adopted Brutus from South Philly one month after he was born, and we've been the best of friends ever since. I always have to work so much so I felt bad that there was no one for him to play with during the day....
