Cute! Probably something else back in there (which isn't uncommon as JRTs are less a breed and more a type) You can get the craziest throw backs even in the most well bred of litters.
Sucks about they hyper though. Mine are all active, but none are hyper.
(I love speckles.. have you seen pics of Kat?)
I know, Im sure is a mix of something else. Oh no, it doesn't suck that they are hyper. It just makes a more livley household, lol. They are a lot of work but I love them so much. It may be a challange but I couldn't ask for anything better, I would not trade them for the world.
I have not seen a pic of kat.
The speckled one is Rocky. She is more mellow then Jack.
