Norma the cat is now suffering from age-related hearing impairment. In her youth she could hear the sound of a tin opener from 100metres and would come running before the lid was off the can. Now even when I call to remind her that it is dinner time she doesn't hear and I have to go up to her, tap her and show her the food before her youthful excitement takes over and she runs to the kitchen, (or at least attempts a run!)
Mandi on the other had has a new game called 'pat the window blind'. He jumps up onto the window sill and pats at the venetian blind so that it makes a noise. This and the 'tap the lever on the office chair' game keeps him occupied for hours.
