We were told by a surgical specialist, most tumors that are taken out come back even bigger.
I know from what was explained to us, chemo and radiation is brutal on animals and very expensive.

Fact the tumor is growing so fast in last 5 months, unfortunately is not a good sign. It doesnt take expensive testing to figure that one out.
Yes, Mr. Meow is doing so well now but the tumor will start to effect him.

Enjoy the time you have with him. Give him lots of attention and kisses, I personally would not put him through surgery since it's growing so rapidly.

Your heart will tell you what is right to do, Mr. Meow will let you know too.

Will keep him/you in prayers.
