So...Spud hadn’t been quite “right” for the past few days. He was still eating, but one eye kept getting gunk in it, and he got very stained round the mouth/chin with whatever he ate. His weight was fine, and I kept a close eye on him. This morning, saw he was very wobbly on his legs. Was up before the vets were open (had to go somewhere early), and rang them as soon as they were, managing to get an appointment for lunchtime.
Unfortunately, Spud died before that appointment. I don’t think he suffered, well, I really hope he didn’t. It was a shock, but I’ll be okay.
