Thank you for answering,i took him to the vet because he just kept crying,he didn't seem to know what he wanted.He does have dementia but i didn't know if this was connected,the vet felt his kidneys and liver,and thought they didn't feel right(think i'm repeating myself!)lol Amazing,when i brought him home,you would have thought i'd got the wrong cat,i think Charles maybe has healing hands,as he'd-Bryn-just settled down stretching out and relaxing.I'll let you know what they say after the scan.
