One minute he's his vocal and happy self next minute he is wonky on his feet and just doesnt seem to be with us,as if he's in somekind of daze. He sleeps with me at night and last night he just couldnt get close enough to me where as usually he sleeps on the pillow or under the douvet but with his back to me but last night he insisted on being really close to my chest but he didnt rest his face under my chin like he does,it was like he was sleeping but not in a comfortable way,only just lying there but not relaxed. I know this may sound really odd but I am really worried about him,he had bloods done earlier this year and they were good for his age(he'll be 19 next week) but I cant help but think old age has really caught up with him. He's eating and drinking fine and using tray etc
