Thanks folks.
Oscar was fully vet checked in February by the UKRCC when all his bloods were done and again by my Vet in March, which I realise was a while ago now but his eyesight was a problem back then and they didn't pick anything up. It was the first thing my vet looked at, he did give him a thorough check and seemed to peer into his eyes from every angle optician style and said it was nothing other than age related failing eye sight. Oscar doesn't really keep the best of health anyway - he is also very snuffly and was at the vets just last month and had acourse of anti-biotics and again the vet checked his eyes. He also is very stiff - another thing the UKRCC Fosterer had noticed before I re-homed him - when he first gets up and has a walk about he is very stiff and shaky on his legs. Both cats are meant to be the same age but I would easily place Oscar a good five years older than Edgar, in fact I could place him ten years older than Edgar!

I think he does still see some light and shadows but at times does seem confused when I talk to him and seems to look about for me. He is not very steady on his feet at all though and the highest he jumps is couch level and even then he comes off backwards (something I had never saw before) perhaps because of his eyesight or because of his legs, either way he stretches down a leg to touch the ground before he comes off - cute but bizarre!! He actually fell off the couch once as he didn't find his footing - I felt awful even though it was his own doing and he upped and trotted off...as I said he is just an unsteady wee blinding bunny!!
I will def try the noisy toys - I also actually have some of that cable stuff that binds up boxes after a delivery today so will give that a try.
I just worry he is not happy - I know he likes cat nip so I might try giving him that a bit more often and maybe make a habit of grooming him every day rather than the normal 2-3 days just for the extra contact - although he does tend to swipe if you hit a not - had a few nasty cuts that way!!
Thanks again for the advice and I will go check out the link posted also - and any other ideas are much appreciated!
here is a wee photo of the man, just cos I have got all soppy talking about him! - my friend says he looks like 'naebdays bairn'
I think you will agree his whiskers are certainly good enough to get him about
