My cat just semi-collapsed. Her back end went completely limp and she had urinary incontinence which she has never had before (she is 14). She was conscious but appeared 'stunned'. after 10 mins or so she was able to slowly walk but seems very unsteady. She is booked in at the vets in the morning as she keeps getting recurrent bouts of stomatitis which are being treated with steroid injections/antibiotics. Is this linked or something new?
