my cat is 15 but iâ€[emoji]8482[/emoji]ve only had her for a few years and she hasnâ€[emoji]8482[/emoji]t been well during that time. she eats a lot but is very thin. she sits out in the heat or the freezing cold. the vet prescribed some thyroid medication several months ago, but it doesnâ€[emoji]8482[/emoji]t seem to have helped. she is vomiting and defecating a lot. she is unable to maintain her thick coat and she has faeces in it. she smells really bad. for the last several months her personality has changed and she hasnâ€[emoji]8482[/emoji]t wanted to spend any time with anyone. the last 2 weeks she has gotten worse. my mum thinks she is miserable and in pain and that we should put her down. i donâ€[emoji]8482[/emoji]t know what to do, id like some advice. thank you.
