He had been off his food for a week or two and not been out far for a little longer.
In truth, he was just short of 18 years old so when he started to lose interest in things, I suspected that the writing was on the wall.
Long story short, I had to take Thomas to the vet yesterday as he was suffering. After examining him, they could offer no positive indications. Weighing things up, I had to make the awful decision that pet owners sometimes need to make. Heartbreaking...
Thomas passed into the big sleep while I gave him cuddles.
Massive tears here, but on balance it was the kindest thing for him.
