can anyone offer me some reasurrance as i feel im going crazy, i got a male rescue cat 2 years ago called sid who was 12 at the time, i live alone and he has meant the world to me, i loved hime more than life itself, sometimes even at work i would want to be at home just to be with him! (odd i know!) - probably over the passed month my dad and sister both mentioned how old and scrawny he was looking, however it was put down to age, i had noticed some blood coming from his mouth and made a note to book him in at the vets, a few days later, he still hadnt gone and he suddenly seemed really quite bad and struggled holding his head up, the vet saw him the next day and had to re-hydrate him there and then, he has since been back a few days later and they took him in for 4 days to keep him on a drip for kidney failure and high blood pressure, when i went to pick him up he was like a different cat, so thin and unmotivated, two days later i had to put him down, that was moday just gone and i am constantly thinking how he may have made it if id just have taken him a few weeks before, i miss him so badly it hurts and just want him back, the guilt and pain is killing me - can anyone help??????
