I don't know what to do about my Mum's cat. Since she's had it the cat has been the love of her life. It has a litter tray and has never been allowed out. However Mum has started filling the litter tray with stuff (this morning it was two boxes of cat food sachets, two toilet rolls and some soft toys) and turning the litter tray round so the entrance is against the wall. This means that the cat can't get in it. It was cleaned out on Wednesday but I can see that it hasn't been used since then (not it's fault poor thing). I am worried about where it is using instead. Mum won't let it out of her bedroom and I have a horrible feeling it might be using her bed which has all sorts of things on it (duvets - more than one and including one I know is 35 years old, baby cot covers, blankets, clothes). However when I tried to suggest that I investigate I was thrown out again. Also she has not been giving it water so on Thursday I gave it some water, but yesterday she had replaced this with a cup of coffee (it would be funny if it wasn't so sad). If I try to do something about it she gets angry and agitated and when that happens she refuses to eat for the rest of the day. She has so much stuff hoarded that she only has little pathways around her bedroom and I would have to physically manhandle her to get past her so I just have to leave and walk away. I don't know what to do.
