We had to have all the cat have a sleep over at a friends house. could this behavor have anything to do with all of this Hope someone can help us

It is very common for siamese to have a crossed eyes appearance...it is probably the siamese in him. As far as the nervousness goes...some kitties are jumpier than others. But there are many products on the market that can help. Feliway is one of them, I have never personally had to use it but I hear it is very helpful.
