They are extremly close they just look at eachother and know what the other is thinking. They haven't cuddled yet and the people i got them from said Blotter will cuddle but Boomer won't. Boomer only likes to be petted on his terms otherwise he runs. It's so funny to see how different they are with me and my boyfriend I can only pick up Boomer without him jumping down and my boyfriend can only pick up Blotter.Silly Boys!
