My male cat is suddenly refusing food and hiding. He is usually a greedy velcro cat, so this is worrying.
Yesterday, he seemed fine, eating normally, very cuddly and was out hunting mice (we live rurally).
His sister was PTS two weeks ago as she was suffering from kidney failure, now extremely worried something is seriously wrong with him too. I don't think he's grieving for her as he was a bit of a bully to her and has always been far more pally with our dog for some reason. He doesn't like being alone, but he always has company either human or canine, usually both. Family were visiting and recently left, so don't know if that plays a role? He was very happy with their presence - demanding cuddles and strokes.
Any tips? I don't know whether I should rush him to the vets or give him a day to see if there's any improvement?
