I am refering to DSH's, not breeds specifically known for them.
Taz, our big, orange, 11 year old, indoor, neutered tom has them.
He is 19 to 20 pounds and is big, not very fat.
He has ear tufts 3/8 to 1/2 inch long (won't hold still for measuring )
He showed up here at 12 weeks of age so I don't know the "lineage", he is just about the size of a Maine Coon but I don't think he is one.
When he showed up, his tail was injured and infected so the vet had to amputate it, leaving a Lynx or Bobcat sized tail, the ear tufts add to this general "wild cat" appearance Look deceive thought, he's as domestic as they get.
