Pepe was part of a litter of 5 for this foster and they were all incredibly rambunctious (in a good fun way!) They showed no nervousness or skittish behavior - in fact, they were extremely attached to any person who came their way. And by 'attached' they literally would attach themselves immediately to clothes, legs, arms, etc - the higher they went, the more comfortable they were! Foster said they would all try to sit on her shoulders and head and try to knock the other ones off. They were all very good jumpers and could easily balance on small, high toys! (top of a scratching tree measuring 2" in diameter!) They are extremely curious and adventurous!
