My 16 year old cat has been unwell for a few months. She has lost most of her body weight and is mostly bones but she never stops eating. She keeps pooing everywhere which recently has become a lot less solid. She occaisionally sits on my knee but spends most of the time in the kitchen waiting for more food. She has 2 different pills one for her heart and one her thyroid. I just dont know what the best thing is for her.. I am taking her to the vets again on saturday but worried what they will ask me to choose. What would you do? is the fact she wants food a good sign that she has fight in her?
