Thanks, and sorry about your kitty.
My puppy is actually 7 years old. I just realized how that sounded. We call our dogs "the puppies" and it never occured to me to call him anything different.
One of the tumors is sort of under his armpit, and he will have to go up and down a full flight of stairs to potty. He also loves the sofa and bed, so this is going to be rough on him. (he's a wimp and a baby anyway!)
