Aww he is so beautiful! I used to have a lop that looked just like that, though she was 1/4 rex and her seal point colouring came from that side of her family. Her dad was like a siamese cat in colour, so lovely.
Like racinghamster said I do think you should get those teeth checked out at a vet - if he didn't have any hay he could well have dental issues as you know. I had a rabbit with a weepy eye and he had a huge abscess. It makes the eye weep because it pushes on the tear duct. Having been learning all about small animal dentistry at uni this last week I wouldn't chance leaving it if I'm honest!
I like Monty as a name
