Well, got Liam back around 6pm last night. He was a bit wobbly and sorry for himself ... and has a strip of fur shaved away around his neck where the lump was. The lump is now gone and two stiches are in its place.
I have to take him back again on Monday so the vet can be reassured that his wound is OK ... then the following Monday the stiches come out. He's being really good and not trying to scratch at his stitches.
And yes, before you ask, from Thursday I will be able to pause and rewind live TV.
