My cat's surgery

Edit:
There's no chance of him living, he can't be able to eat or drink...we are going to put him down in order for him to live in peace.
Bud Bud is one of the greatest cats we have ever had so far and considered the best. After me and my mum's appointment, we are taking him to the vet to put him down and get him cremated...if he died "naturally"...then we'll have to bury him at the front yard without the kids looking. I'm expected of him to be alive one more time and then put him down and cremate him, then his ashes will be with us...
We first met him when me sister and her friend saw him on the streets; just being a normal cat. So they thought "Hey, why not give him sausages?" And so they did. After weeks of deciding to will keep him, they thought my sister will do since we took take of cats before. One or two years later? (Sorry, my memories suck) and he's here suffering this own pain...all from some "criminals" that used the chemicals in grasses (he loves that btw, and thought it would be good for the system) but I don't think he's the only one, if fact I think another ran off to die on his own...don't know though.
All I know is that; After the appointment, me and mum will take him in, I will see the pain of him being eased and I hope he doesn't die tonight, otherwise we won't cremate him (and we're thinking of moving because I don't want to go through this again, I'll tell you the reasons why in another time).

Until then, I will be on hiatus. I will only comment and such, or not depends if I will accept it...

My cat is in need of surgery in order to power through an infection that started in his mouth. One or some of you may know him but his name is Buddy, or Bud Bud, a lot of you would be confused and say "But it's a girl right?" Well we were wrong and the doctor told me mum that it's a boy, and a three year old one.

I actually made a Gofundme page for you to either donate, or spread the word (or both if you want, I usually do that all the time, but this time I couldn't be able to donate one time due to uh...other charities )

gofundme.com/33b8amn8 <- Here it is if you want to see it, this is my first time doing it but it's for a family member...to protect and care really.

So if you have the time; Donate some money or spread the word
Even $1 would make a difference, I know it will, I just know it!

thank you for your time reading this and I hope you have a lovely day
