My cat is 17yrs old and it recently came to light that she has hyperthyriodism and was given tablets for it.After 21 days on the tablets she had a stroke that was one week ago.She is on blood pressure tablets and steriod tablets now but she finds it difficult to stand and get up and down on the bed/chair and tends to stagger/fall quite often.Should I have her put to sleep or is it worth waiting to see if she will recover.If I wait what sort of time would be required before I would see any improvement if at all possible.
