We fell in love with Jack and his brother Sam at a pet shop, and although we only really wanted one more  we are glad that we went for the two.  They were inseparable during their kittenhood, and still spend a lot of time together. 
Sam is very friendly, apart from when he is trying to sleep when he can be a little grumpy.  He spends most nights asleep on the bed, apart from when he is out hunting.  He keeps trying to improve our hunting skills, by bringing in live mice for us to catch in the early hours of the morning!
