Thank you everybody
You're right about her field of vision Mark ... I have found so far that she doesn't bump into things she can see head-on, but things will happen like today she came running round the corner of my neighbour's house when I got home from work, which was on her right, and bumped her head as she obviously misjudged quite where the wall is. She also has to turn a right-hand corner from my hallway into the kitchen and regularly collides with a plant. Luckily she has a hard head and still has a long way to go before she becomes as brain damaged as Bertie
I am really, really relieved that it's nothing that can get worse though - I hate the thought of my poor baby going through any more than she already has this year. I do wonder whether her previous owners knew she was blind in one eye, bearing in mind that they owned her when the apparent accident happened .. if they did know, it makes it even more unbelievable that they emigrated without making any arrangements for her
