Well, when we had Brando (Zsa-Zsa's late brother ) and Zsa-Zsa was fit and healthy, they both loved the outdoors, travelling about the park near our house and having a good stroll throughout our neighbour's gardens. Brando used to have a gentleman's lounge with his friend Yoda, a cat who still lives and belongs to one of our neighbours, and Zsa-Zsa used to love climbing along fences and generally being in the warmth of the sun (when we did actually have sun!). So i was never paranoid then, the cats clearly enjoyed having a little independance and free-time. Well, old age began to set into Brando, so he began to venture no further than the garden, although Zsa-Zsa would still venture out. But then, just after Brando passed away, Zsa-Zsa went blind. I daren't let her go outside save for the garden now in fear of losing her. She could become disorientated and lose her way, get attacked by dogs as she wouldn't see them coming, wander into a road... the possibilities are too much to think about. But i swear that even though she is blind she knows when the front door is open, as if anyone comes to the door she's there and attempting to get out. We thought about getting her a collar with a tag stating that she's blind in case she did ever get out, but being a very dignified lady she won't have it. So yes, i do get a little paranoid now she is blind. I never doubted her sense of direction before her disability, but now i would tear myself up thinking about her if i let her out.
