Help Needed for Charlotte

We will be getting Charlotte back after almost 4 years from what we thought was her forever home.  When she was adopted, they understood that she needed to be an only cat.  So, last year, they brought in another cat and now Charlotte is the one to suffer.  She has been having issues with her skin and using the litter box which I think is all behavior related. 

 

So, we need a foster home or at least a room for her so we can get her well.  Please help spread the word.  My house is beyond full and I’m down to a bathroom which works for a couple days but not much longer.  I’m attaching a picture and bio for you to share.  I appreciate the help!
