hello!
 I am desperate! I have a two year old cat, she is a female. I also own a male cat that is twelve years old. 
The female cat had an infection and she was taken to the vet and they prescribed her medicine, one was an antibiotic, the other was for the infection. After she started taking this medicine she's been having diarrhea. She has been pooping outside of the litter box!! Imagine the mess to clean up. It is awful! After the medicine, the diarrhea and pooping outside of the litter box continued. I brought her to the vet again to see if it was something serious. They then prescribed the same medicine with a probiotic, she was on it for two weeks. It helped a little, after the third visit they gave her special food. Thankfully, her poop is now normal, but she is still going outside of the box!! My family wants to get rid of her. I don't know what to do. I thought she was going outside of the litter box because she was stressed from the sickness and medicine. I also bought three new boxes, with three different litters for her to choose from. They were all put in different parts of the house for her to choose from. She still goes outside of the litter box! It is right next to the box. I have also seen her scratching around her poop as if she was trying to cover it with litter, I don't understand why? She has pooped outside the box a couple times before her infection, but then she began going inside the box. I don't know what happened. 
Please help! I am running out of options. 
I don't know if this has an affect, but there is two outdoor cats that come by my house and she get fluffed up and uncomfortable.
