Input: Throw away account since my sister is on here. 

My sister begged me and my husband to take her cat when she moved into a sort of mental halfway house. We took her on the condition that she would pay for her food, vet bills and that she was healthy (not pooping and peeing outside the litter box). We live in an apartment, and paid to have her cat added to our lease. It has been about a year since she has been here, and my sister has not paid a dime for her care. Her cat is also pooping and peeing outside of her litter box, and when I've mentioned this to my sister all she says is "please don't get rid of her". She does not offer any suggestions nor offers to take the cat to the vet. I have asked her if she knows anyone who could take her, and she claims she doesn't. Our apartment smells AWFUL because of this cat, and it is really stressing me out because I know we will never get our security deposit back and we have a small child we also has to smell it. We've paid to have our carpets treated, and we've paid for flea medicine as well as having our apartment treated for fleas. My sister has not offered to help with any of the cost. Would IBTA if I gave my sister an ultimatum that she either finds somewhere else for her cat to live, or we will take her cat to the no-kill shelter near us?
