Unfortunately he passed away this weekend. He seemed perfectly fine on Thursday, running around the house, then on Friday he was dragging one foot behind him, and this morning he was very poorly.
From what the vet said, it looks like the growth found in April suddenly caught up with him and was pressing on the nerves in his abdomen. He was still trying to follow his old routines, like walking over to his food bowl and leaning on it to check for good stuff, as though he didn’t realise his back feet weren’t working. I guess if the growth interfered with his nerves, he wouldn’t be able to tell.
I shall miss having him sitting on the sofa, washing, sleeping or just hanging out, while I’m writing.
