Hi Bee, i am sorry for getting back so late to you, I am a owner of a deaf cat and if there's any advice i can give i can try and do my best.
By the way your cats look like Turkish Angoras, Well as i can see that your two have totally different personality's.
My Girl because she is deaf she has a naughty streak thinks she can get a way with it
, She sleeps a lot and sometimes she can be a little jumpy but that's rare. She has 100% missile target lock on for eyes, small moving things will get her really excited!. i will need to read your posts.
