Yup, came here for this. Programmers and rubber ducks are proof of this concept.

I had to put my 17 year old cat down 4 weeks ago. She was suffering and in pain. I know you want to help her and this isn't the answer you are looking for, but you really need to consider the quality of kitty's life, and the toll her care is taking on you. The kindest thing you can do might be to say goodbye. I'm so sorry.
