Thanks Ann-Marie , I think it is a combination of the radiator (as the elderly always have their house at near boiling point ha ha) and maybe the parrot mix being fed?
She is a lovely lady , but very errrr, strong willed I'll call it that :rofl: will have to approach the subject delicately with her... She has had him to the vets who have checked him, blood tests, weight etc etc but they say he is perfectly healthy. I am meant to be looking after him in June for a few weeks.
Any ideas then Ann-M as suggestions to help?
