>>108018420That very slim face with a very pronounced snout and nose looks like a Siamese which also matches the colours of his fur. Especially the face, once again, and his paws. However, both Siamese and Burmese usually have short hair, but Bootaro is very fluffy. While Burmese may have a similar face to Siamese, that's pretty uncommon, it's usually less pronounced compared to Bootaro.
Both of these don't quite fit him and it's also not like he looks like a mix of these two specifically. I agree that Minto doesn't seem like the type who would go to a breeder to adopt a cat.
