Thanks everyone. I feel sad and while I know he had a good life playing in trees in our garden with his brother and being utterly spoilt with steam chicken thigh fillets, baked salmon or grilled steak for dinner I feel he deserved a lot longer than he got.
His brother is still out of sorts a bit with a sad look on his face, but not walking around calling for him so I am sure showing him his dead brother was the right thing,
Hopefully Sean Connery will give him a pat for me.
