My oldest daughter has a beloved Maine Coon mix who won't use the litter box. The story is kind of an eye roller, but she lived with her SO's mother and SO for a few years so they could save money for a house, which they did. However, his mom is really sweet, but not very bright and she put pads all around for the cats to do their business on (she has an assortment of animals) and my daughter's cat apparently got used to that. She had a litter box, but now daughter is thinking she didn't use it with the pads being easier. Now that they are in their own home her SO and her are going ballistic because the cat refuses to use the litter box. My daughter really loves this cat and has tried everything she knows. Do any of you cat lovers have any suggestions? She doesn't want to have it put down. Would a rescue take a cat who won't use the litter box? I'd pay the surrender fee for her but somebody told me that nobody would take her because she'd be unadoptable. Any rescues in Illinois? Help?
