It's definitely..........
A bunny.
Seal point is colour and markings, not a breed, isn't it? He isn't a seal point I don't think, colouring and markings are wrong.
The markings are 'fox', I believe, like my Annabella. Although it is hard to tell from the photos, because if there is an orangey or yellowy tinge then it would be otter... but the photos seem to show all white underneath and around the facial features.
No idea on breed, but if he isn't from a show breeder he is likely a cross/mix. His coat looks short and lacking in guard hairs but not as short as a rex's but again it's hard to tell from those photos.
Yeah, my OH looked at the pictures and said that he was pretty certain that your rabbit was the same breed as Lily. We decided that she must be Perlfee because we spent months trying to compare her to other breeds and it was clear that she didn't really fit with any until we saw a picture of someone's perflee, and we knew instantly that this is what she was. If you have found the same thing, then I would also think that yours is a Perlfee too. Trying to find images of them is quite tricky because it turns out they are considered to be quite rare, but try to compare Bunny to as many Perlfee images as possible. Then you can feel more confident about it.
