Tan I am going to be a bit blunt here cos I think you really do need to stop listening to this woman..
Its almost unheard of on Purrs and actually I dont remember a single case before, where a number of people on Purrs have actually tried to give advice to an owner to send their cat to the Bridge.
We feel that its not our place to do this normally as we are not vets and do not know the cat, its a decision only the owner can make for their very best friend.
I am sure that you know that all of us have dearly loved cats and often more than one. Most of us have been in a situation of having to give the greatest gift of love to one or more of our cats.
I was so close to making this decision for Franta in February but I was so lucky cos two magnicant vets were able to save his life but he was not at the stage Milo was and as far as we know he does not have a tumour cos he responded to some very harsh abtibiotics that worked in his brain. This is quite an unusual case and know that others have hung some hopes that some similiar treatment would help their cats but sadly it will not.
Milo is at a stage by your description, that he is suffering terribly and has now given up and he is asking for your help in setting him free from the pain and the hunger. I have tears running down my face writing this but please let him go to the Bridge.
Guilt is one of the phases of grieving and am sure that nearly everyone of us has had some guilt after letting our cats go, it maybe guilt cos we didnt do it soon enough or because we thought we were not able to help by getting better treatment or just from our lack of knowledge.
The pain that we have is cos we love someone so much but the greatest gift we can give our cats is trying to do the best for them when they are so very very ill and often our pain is their lack of pain and the freedom we give them to pass quickly and safely to The Rainbow Bridge. They will always leave their paws in our hearts and it will be painful for a very long time but you will get a message from them to say they have arrived and that they are free and playing again.
Please do not leave this any longer or you may have to deal with a much worse scene than you now have and you will never forget what you have put Milo through
