Hey Elizabeth, we have a friend for your sunny boy, this poor cat was a stray who adopted one my quilting buddies, for now apparent reason his eye developed the same sounding problem as sunny boy and he had to have it removed too!!
Here in Spain they are a word which purely means 'one-eyed' -TUERTO!!!
So that has become his nickname now!! Heres a picture of him with his mum, Jan, not long after his operation. He gets along just fine without it!!
