To update. Daffodil improved with the Beryl's but was still drinking huge amounts of water. This continued until she was only drinking water. She lost half her body weight in one week. Her feet got more swollen and she stopped talking two days ago apart from the occasional purr. She was struggling to move at all and refused all treats, even corn and cherries, except egg. This morning she was found sleeping in a lake of urine and when bathing her to wash it out she had a fit and minutes later died, seemingly very peacefully, in Rosie's arms. She seemed to enjoy her last few months and was always full of beans and very alert but her body just finally gave up. She will be missed, as all our losses are.
