Again, thank you all for your kind thoughts.
I am pleased he hopefully had a quiet path but am now starting to worry what caused his death as he'd seemed fine over the weekend and had quite happily played in his ball on Sunday when I cleaned him out, was still after as many treats as he could fit in his pouches and he was only around the 11 month mark.
I had earlier in the year posted about his health but a visit to the vets (which he hated!!
) showed nothing and his little baldy patch had started to regrow. Clearing his cage showed no loose stools or any clues as to the cause of death. Am hoping it's not anything genetic as I have another little boy from the same litter and really don't want to lose him as well.
