Yes I wondered that too Cypher and I do think that part of it is just his personality, like people they can be very different! He's a very sweet boy though and I'm hoping that at the least we can get him to feel safe in his new cage (I'm trying not to get too excited in case it doesn't work!). The Chinese litter sound lovely and I guess is proof that they're not all the same even when they've been treated the same
