Actually he was DS1's budgie, but I looked after him. He was only 3. I don't know why he died; he was fine last night, tweeting away. This morning I noticed he was asleep on his perch with his head under his wing at a time when he is usually awake (when the house was full of noise) and early this afternoon I noticed he was sitting there looking all puffy, dull-eyed and miserable.
DH took him out to look at him and we could see he was unwell so I planned to take him to the vet this evening when I had got back from visiting my dad in hospital. We had trouble getting him back on his perch but he went on eventually. Then, while I was out, he fell off. DH held him in his hand and within a few minutes he died. I have no idea why.
The kids were so upset when they got home; even DS2 age 6 (who is a boy of few words due to his SN) asked if "Spike had gone to heaven". Sob!
DS1 has buried him in the garden. It's so quiet here this evening; his cage was above the pc and he would tweet away going "88! 88!" (we never knew why!), "Pretty boy!" and "off to Tescos!" while I sat here Mumsnetting.
Rest in peace Spike.. you were such a character.
